Arsenal are in for a very bumpy ride this January transfer window.

It's been a tough start to 2018 for the Gunners having drawn at home to Chelsea and then lost 4-2 to Nottingham Forest in the FA Cup.

Sunday's defeat at City Stadium was nothing short of embarrassing and means Arsenal's season is now in jeopardy.

They're still in the Carabao Cup and going strong in the Europa League, of course, but Arsenal fans had hoped for better heading into the 2017/18 season.

And it would appear the worst is yet to come. According to the Telegraph, Manchester City have decided to make a move for Alexis Sanchez this month, rather than in the summer.

Pep Guardiola was originally going to wait until the summer transfer window to sign Sanchez when he becomes a free agent, but they're now weighing up an offer.

Arsenal want at least £35 million for the Chilean - who was the subject of a £60 million bid from City six months ago - and a replacement lined up before they consider selling, though.

But who could Arsene Wenger sign? Thomas Lemar is a long-term target for the Frenchman but he seems to favour joining Liverpool.

Leicester City's Riyad Mahrez has also been linked with a move to the Emirates Stadium and would be a fine replacement for Sanchez based on current form.

Well, the Telegraph claim Arsenal are watching one player "closely" in particular and could make a move if Sanchez departs: Nabil Fekir.

Fekir, 24, is one of Europe's hottest commodities at the moment having scored 30 goals in 18 months for Lyon and has attracted a lot of interest recently.

Arsenal were rumoured to be making a £60 million move for the France international back in November and now it seems their interest is strong.

It all depends on where Sanchez - among others with six months remaining on their contracts - ends up this month, which Wenger alluded to in a recent press conference.

"We are open in any position for the exceptional player who can give us a plus," explained Wenger.

"I must say it depends on who will manage to extend the contracts of the players who are on the end of their contracts in June.

"We will have to take the consequences of these decisions and respond to it.

"In our jobs sometimes one day you think you've made progress and the next day you move back again, so as long as something is not signed you don't like to talk too much about it."
