United will monitor Alexis Sanchez’s situation after the Chilean forward became a target for Arsenal and Liverpool.

Louis van Gaal is an admirer of the Barcelona star, who is set to leave the Nou Camp this summer following the expected arrival of Luis Suarez.

The Reds’ new manager has already spent close to £60m on the signings of Luke Shaw and Ander Herrera since being appointed David Moyes’ successor, but plans to carry on spending big in his bid to challenge for the Premier League title in his first season in charge.

He wants to strengthen in the centre of defence and midfield, as well as add pace and width to his attack.
