Alexis Sanchez has not travelled with the Arsenal squad to face Bournemouth, increasing speculation that the Chile international is set to leave the club.
The 29-year-old has been heavily linked with a move to Manchester City, with his contract due to expire in the summer.
But reports this week suggested that Manchester United are attempting to trump their local rivals with a £25million bid and a wage offer of £400,000 a week.
Arsenal face Bournemouth at the Vitality Stadium on Sunday afternoon, but Sanchez has not travelled with the squad despite no reported fitness issues.
Fellow Arsenal attacking midfielder Mesut Ozil is also out of contract in the summer and has also been linked with a move to Old Trafford.
Manager Arsene Wenger admitted earlier this week that Sanchez is unlikely to stay at Arsenal due to a desire to win major trophies:
” It looks like Sanchez will not extend his contract.These guys want to win, and they want to make money as well. So they want a combination of the two that big clubs can give them. Incidentally he’s won trophies with us. So he wants to fight as well for the Premier League, that’s normal when you are at that level.”
And former Manchester United full-back Paul Parker, in his Eurosport column , said that he completely understood Sanchez’s desire to leave Arsenal.
“You might think his behaviour this season has been petulant, selfish, arrogant; but to me that suggests he’s a frustrated winner who is desperate for trophies,” Parker said. “It’s not just about money for him.
“Sanchez appears to have two possible destinations: Manchester City and Manchester United. At the former he’s guaranteed quick success; at the latter he has the chance to be the game-changer and hero. Until he became a contract rebel at Arsenal, it looked like he thrived as the star man – working extra hard to get the ball and make things happen.
“Maybe he’s had enough of that. Sanchez wants to be around players who are as good as him, maybe even some that he believes are better than him. As good as it is being Superman, it’s time he fitted into a team with a few Supermen already there.”
