9 of the Best Premier League Deals That Were Officially Completed on Transfer Deadline Day

On a crazy day of transfer activity, Tottenham and Swansea appeared to be the victors of the deadline day rush - while Chelsea and Arsenal showed that poor planning and a late-dash for the finish line can lead to some real frustration.

Last year's FA Cup finalists failed to snap up their chief targets, with the Gunners failing with a alleged £92m move for Monaco star Thomas Lemar, while Ross Barkley took a dramatic U-Turn to stay at Everton for at least six more months.

Nevertheless, while there were some failures, success also took place on a chaotic day that twist and turned as agents and fans button-bashed on social media to see whether their stars have signed.

Here is a round-up of the best deals to go through on the final day.

9. Mamadou Sakho - Liverpool to Crystal Palace (£26m)

In the early hours of Friday morning, Crystal Palace finally got over the line the transfer deal they have been working on for the majority of the summer - wrapping up the permanent capture of last year's loanee Mamadou Sakho.

After failing to impress Jurgen Klopp while on loan, Liverpool sold the troublesome French international, leaving the door open for a second attempt to try and lure Virgil van Dijk away from St Mary's stadium - or at least that's what people thought.

Nevertheless, in getting this deal done after the transfer window shut, Crystal Palace can now focus on tightening their defence - with Sakho key to ensuring they remain resolute at the back to avoid another relegation scrap.

8. Danny Drinkwater - Leicester to Chelsea (£35m)

Chelsea got over the issues surrounding a failed transfer deal for Ross Barkley by ending a long transfer saga to snap up England midfielder Danny Drinkwater.

Signed on a five-year contract from 2016 Premier League winners Leicester for £35m, the England international, who featured 35 times in 38 league games in a sensational against-the-odds title win for the Foxes, was a mainstay in a team that shocked the world two seasons ago.

Now reunited with former midfield partner N'Golo Kanté at Stamford Bridge, Antonio Conte has added further strength to the centre of the midfield for Chelsea after signing Tiémoué Bakayoko earlier in the summer, while also keeping hold of Cesc Fabregas.

7. Wilfried Bony - Manchester City to Swansea (£12m)

The Ivory Coast international has returned to the Liberty Stadium after departing in 2015 for the Man City, in a move which has stagnated his career. While in Wales, the burly striker was a threat for the Swans, while causing havoc to defences across the country with a tough nature and eye for goal.

While at Manchester City, he failed to break into the first team as the forward struggled with his  hefty £28m price tag. Now back at a team that fully appreciates his qualities as a striker, his £12m purchase looks an astute one after seeing Gylfi Sigurðsson jump ship to Everton. 

If he can recapture the form that made him a household name for Swansea in the first place, it might the catalyst that keeps them up for another season.

6. Tim Krul - Newcastle to Brighton (Loan)

The Dutch penalty-saving master has been brought in by Brighton on loan to provide competition for new signing Mathew Ryan, who will be still finding his feet after signing from Valencia.

Manager Chris Hughton knows the Netherlands international well having worked together at Newcastle, describing the 29-year-old as an "excellent professional."

His experience could prove vital if Ryan struggles in difficult circumstances, as they expect to battle against relegation.

5. Davide Zappacosta - Torino to Chelsea (£23m)

Everton contract rebel Ross Barkley, Alex Oxlade-Chamberlain - who preferred Liverpool - and Fernando Llorente, who opted for Spurs, all rejected the chance to join Chelsea in the closing hours of the window. But manager Antonio Conte gave the thumbs up for Chelsea officials to move for Torino full back Davide Zappacosta.

The versatile Italian is an uncompromising defender who can play on either side and will provide excellent cover for Marcos Alonso on the left. At 25, the full back is entering into his prime years, which Conte knows full well, and adds extra cover for the Blues as they seek to defend their title.

4. Fernando Llorente - Swansea to Tottenham (£12m)

In what will look like a bargain buy, strengthen the Spurs in a push for the Premier League title and provide a steady second option to compliment or replace star man Harry Kane when he needs to be rested, Daniel Levy worked his magic again in the final hours of the transfer deadline to snap up former Athletic Bilbao target man Fernando Llorente.

With bags of top-level experience, able to play with his back to goal and incredibly strong in the air, Llorente could be a key component in the final third across all competitions for what appears to be a paltry £12m fee.

3. Serge Aurier - PSG to Tottenham (£23m)

Serge Aurier's arrival could be an excellent move for a Spurs side that has been in desperate need of some transfer business to bolster a small squad. 

After the £40m capture of Davinson Sanchez and promising defender Juan Foyth on the penultimate day of the transfer window, Aurier - who arrives from PSG - offers serious pace and attacking intent to an already strong defence.

While he has hit the headlines for the wrong reasons on several occasions, as a footballer he has registered the highest number of assists in Ligue 1 for a defender with 17 since his move to PSG from Toulouse in 2014.

A fine crosser of the ball who has been linked with Arsenal and Manchester United in the past, the 24-year-old could prove a snip at £23m if he can put his temperamental issues to bed.

2. Alex Oxlade-Chamberlain - Arsenal to Liverpool (£35m)

After putting pen to paper on a five-year contract, Jurgen Klopp stated he was "really happy" with the acquisition of Alex Oxlade-Chamberlain - who can play on the right wing, in the centre of midfield or even at full back if needed.

For £35m it does seem a bit steep for the 24-year-old who has averaged about 17 games a season in his six-year stay at the Emirates, but in today's inflated market, the price tag on the former Southampton man's head could be a sound investment.

If he can put his physical attributes to good use in Klopp's Gegenpressing style, which wiped the floor of Arsenal last weekend in a one-sided 4-0 drubbing, he'll do alright.

1. Renato Sanches - Bayern Munich to Swansea (Loan)

One transfer that may get overlooked but could be a game changer is the loan deal finalised by Swansea to sign Portuguese utility man Renato Sanches from Bundesliga giants Bayern Munich.

With Swans boss Paul Clement familiar of the talent Sanches can bring to the Premier League after spending time as the assistant manager at the club under current coach Carlo Ancelotti, he knows a thing or two about the rampaging star.

When you consider £35m has been spent on a similar player, as Alex Oxlade-Chamberlain completed his move to Liverpool from rivals Arsenal, Swansea have done a fantastic piece of business to add a fantastic addition like Sanches after losing talisman Gylfi Sigurðsson to Everton.
