It has been a very successful summer for Manchester United so far, with Jose Mourinho bringing in three major signings to really bolster his squad.

Romelu Lukaku, Nemanja Matic and Victor Lindelof have all arrived at Old Trafford and the Red Devils finally look ready to mount a title challenge for the first time in the post-Sir Alex Ferguson era.

However, Mourinho has made it apparent that his business for the summer may not be over and it is thought that the boss will look to make one final major signing before the window closes on August 31.

In the past few days, United have been linked with a move for Tottenham left-back Danny Rose after the Englishman's controversial interview which slated Spurs' wage structure.

Nevertheless, it appears the Red Devils have grown frustrated in their pursuit of the defender and have now switched their attention to another Premier League star.

According to The Sun, per Manchester Evening News, Arsenal's Alex Oxlade-Chamberlain is the man now firmly locked in Mourinho's crosshairs.

The versatile England international has dazzled for the Gunners in a wing-back role and Mourinho clearly views him as an asset that could further improve his squad.

The 24-year-old is in the last year of his contract and Arsene Wenger has admitted that he could be sold if the right offer comes in, saying that the board could overrule his decision to keep him.

"After the board has to, of course, agree with me," Wenger added. "And if they don’t agree we have to consider it as well, and I will accept it. But the board is behind me on that."

The former Southampton winger has been linked with United before, with Ferguson registering an interest back in 2011.

"Alex Chamberlain is only young but he has potential. Southampton have done very well bringing young players through over the years," Ferguson said.

"He is another one along with Gareth Bale and Theo Walcott. Before that they had the Wallace brothers and Alan Shearer. They have been good at that. They have done a lot right."
