Manchester United legend Gary Neville is backing their move for Arsenal attacker Alexis Sanchez.

Alexis is being linked with a Bosman move to United next summer ahead of Manchester City.

"Manchester United, in my mind, should always be challenging for the best players in the world and the argument is that always Barcelona and Real Madrid if they do want someone they will get them and that has played itself out over the last 10/15 years but United are now financially challenging," he told Sky Sports.

"They are paying the sums they need to pay to attract the best players in the world. I've not seen the Alexis Sanchez news so you have given me something I haven't heard before but, from that point of view, United, from a general perspective, should always be challenging for the best players in the world and bringing them in."
