Liverpool have expressed their interest in signing Alex Oxlade-Chamberlain, Football Insider sources understand.

The Arsenal midfielder’s future has come under the microscope as he prepares to enter the final two years of his contract.

As revealed by Football Insider last month, the Gunners are ready to begin negotiations with Oxlade-Chamberlain, whose current agreement expires in the summer of 2018.

But the 22-year-old is seeking a 200 per cent pay rise on his current £52,000-a-week wages that will lift him on a par with the likes of Theo Walcott, Jack Wilshere and Laurent Koscielny at Emirates Stadium.

A source close to the situation has told Football Insider that Liverpool have joined Manchester City, Chelsea and Manchester United in asking to be kept informed about Oxlade-Chamberlain’s situation.

Manager Arsene Wenger retains full faith in the 22-year-old, who is rated in the £30million bracket, and does not want to cash in on him in the summer.

Arsenal are ready to hand the attacking midfielder a hefty rise on his current deal, which is worth £52,000-a-week.

But they will stop short of offering the player a deal that will double his wages and lift him on a par with the second bracket of earners at Emirates Stadium.

Oxlade-Chamberlain spent much of the season on the fringes of the Arsenal team before suffering a knee injury that has ruled him out for the rest of the campaign.

Oxlade-Chamberlain did not score a single Premier League goal in 2015 and in 33 matches in all competitions this season, he has scored just two goals and supplied two assists, a poor return for a player who predominantly plays on the flanks.

Sky TV pundit Graeme Souness questioned recently whether Oxlade-Chamberlain takes football seriously enough and says he should be “banging down” Wenger’s door when he is not in the team.
