It's happening again. Just when football fans thought they could relax following the recent Philippe Coutinho saga, Alexis Sanchez's future looks set to take over.Reports previously suggested the Chilean is desperate to leave Arsenal in the January transfer window with both Manchester clubs interested.But now there's been a huge twist in the plot. According to the Mirror, Manchester City are set to pull out of the race to sign Sanchez.City's decision to end their interest has given Manchester United the green light to go all out and get Arsenal's star man.It would be a repeat of the move that saw Robin van Persie join United from Arsenal back in 2012, but the question everyone is asking is why City have pulled out.It was only six months ago that Pep Guardiola was prepared to shell out £60 million on Sanchez, but now he's prepared to let United steal in.So why is that? Well, the Mirror claim it's because City are unhappy with the financial package Arsenal are demanding for any deal to go ahead.However, according to Manchester Evening News' Samuel Luckhurst (see below), it's actually because City have come to realise something about Sanchez that they're not so keen on.Luckhurst explains that City think the Chile international is "prioritising cash over glory" and that's why they're unwilling to push the boat out.

Understandable if true, but it's not like City have ever been against paying their players ridiculous amounts of money.

Sanchez wants £300,000-per-week, so unless he reduces those demands and shows he isn't solely motivated by money, City won't stand in United's way.
