It's not yet clear where Alexis Sanchez will be playing his football for the remainder of the season - but it almost certainly won't be at Arsenal.The Gunners' failure to tie him down to a new contract means he now has just six months left on his current deal.To avoid losing him for nothing this summer, the north Londoners are likely to be forced into selling him to one of their top six rivals.Manchester City came close to signing him for £60million on Deadline Day in August, yet they could be beaten to the punch this time around by rivals United, who will reportedly offer a player-plus-cash deal involving Henrikh Mkhitaryan.Then, on Monday night, Sky Sports claimed that Pep Guardiola's side had ended their interest.In theory, that should leave United with a free run, as the money involved in the deal does not seem to have deterred Jose Mourinho in the slightest - such is his desire to bring in a new number seven.If the Sanchez saga has taught us one thing, though, it's that transfers involving the Chilean are very rarely straightforward.

A new club is in the mix

Miguel Delaney of the Independent has given another update on the situation which is likely to complicate matters even further, as the two Manchester clubs are apparently not the only Premier League teams who have been hovering.

It's now being claimed that Chelsea will make a late approach for the 29-year-old.

Have they been spurred on by City's decision to withdraw? Either way, the news won't be welcomed by United, who will want to avoid a bidding war with Mourinho's former employers.

The Blues have endured three successive goalless draws in all competitions, failing to get past Norwich, Arsenal, and Leicester.

That may also go some way towards suggesting their sudden entrance into this particular piece of theatre.

Sanchez has previously expressed his happiness living in London, which will come as music to Antonio Conte's ears.

Just when United thought they had their man, the latest instalment of Mourinho vs Conte could be upon us.

Who should Sanchez sign for? Have your say in the comments.
