Dele Alli to Arsenal, N'Golo Kante to Man United: Transfers we think would make perfect sense

The summer transfer window closes at midnight (CET) on Oct 5 and the final days of the market promise to be hectic, with clubs all over Europe aiming to plug holes in their squads. There are also a growing number of players who are running out of time to kick-start their careers with a move away from difficult situations at their clubs, having either fallen out of favour with their manager or lost their place to a new signing.

With the ongoing impact of the coronavirus pandemic being felt by even the biggest clubs, the financial implications of a move into the transfer market over the coming days will be significant. But necessity will be a driving force for players and clubs between now and Monday, so which unlikely deals could be mutually beneficial for unsettled players and clubs in need?

Dele Alli, MF, Tottenham to Arsenal

No major player has left Tottenham for Arsenal since Sol Campbell in 2001, so the prospect of Dele Alli making the same journey across north London is slim. The rivalry is so intense that it would take a huge amount of courage on both sides for a move to happen, but at 24, Alli is at a career crossroads. He's been left out of several match-day squads by Spurs manager Jose Mourinho this season, and Arsenal need an attacking midfielder with flair and goals to take the pressure off striker Pierre-Emerick Aubameyang.

Mourinho claims to rate Alli, but he has also made it clear to the player that he believes he is lazy. Alli, who lost his England place last season, has not taken the hint and Mourinho has now dropped him completely.

Real Madrid and Paris Saint-Germain have both been linked with him during this window, but a move to Arsenal might be the best option because there is a clear vacancy in the team at the Emirates. If the move was to happen, it would be the biggest deal of the window by some distance in terms of creating headlines.

Sergio Romero, GK, Man United to Everton

Everton have been the surprise of the Premier League season so far, with Carlo Ancelotti's team going into Saturday's Goodison Park clash with Brighton aiming to extend their 100 percent winning start to the campaign. James Rodriguez, Dominic Calvert-Lewin and Brazilian midfielder Allan have been outstanding so far, but keeper Jordan Pickford has emerged as a cause for concern due to mistakes in goal.

If Everton are to make a sustained challenge for Champions League qualification, they will need to upgrade their goalkeeping options and Manchester United keeper Romero would offer proven quality.

The Argentina number one is available for transfer after dropping to third choice at Old Trafford following Dean Henderson's return from loan at Sheffield United. With Premier League and Champions League experience, Romero could be the man to make Everton serious contenders for the top four.

Kalidou Koulibaly, DF, Napoli to Man United

Napoli centre-half Koulibaly has been priced out of a move to Manchester City this summer due to the Italian club wanting more than £75m for the 29-year-old. But Napoli have also made it clear to the Senegal international that he can leave for the right offer, so he remains available going into the final days of the window.

Manchester United manager Ole Gunnar Solskjaer wanted to sign RB Leipzig's Dayot Upamecano this summer, but the club failed to move quickly enough before the Frenchman signed a new contract with the German outfit. United still need a proven centre-half, especially if Chris Smalling completes a move to Roma, so Koulibaly could be the solution, even if his age and price tag make him an expensive option.
