Manchester United are just 24 hours away from kicking off what could potentially be their biggest game of the season so far as they're set to travel to the home of the champions, Liverpool. The two legendary English clubs currently occupy the first and second spots on the Premier League table and are separated by just three points, and the Red Devils will look to make it six points clear at the top with a historic win at Anfield. Ahead of their high-profile game, here, we take a look at some of the latest Manchester United transfer news.Valencia eye Juan Mata returnManchester United midfielder Juan MataManchester United veteran Juan Mata could be on his way out of the club come summer and is said to be on the radar of his former club, Valencia, as per reports. The Red Devils star, who joined Manchester United from Chelsea in a big-money move, is set to be out of contract come summer and could possibly depart from the club, with it being clear if he has a future at the club. The report claims that Los Che supremo Peter Lim considers this a 'great market opportunity' to strengthen their struggling side and will make an offer to bring Mata back to his old stomping grounds, the Mestalla, should he become available. However, with the club's ongoing financial situation and supporters' frustration over the handling of the club by Peter Lim, it remains to be seen if Mata will accept an offer for a return to Valencia.

Ole Gunnar Solskjaer's side are said to be targeting a move for a defensive midfielder, a forward, and a central defender come summer, with Rice potentially ticking two of the three boxes. 1 - Declan Rice is the first West Ham player to score for England since Matthew Upson in June 2010 (vs Germany).
