Acosta is currently playing alongside United legend Wayne Rooney at DC United, where the pair have enjoyed an excellent partnership in attack. The Argentinian attacking midfielder, 24, has scored five goals in five appearances this season and agreed to join Paris Saint-Germain in January but the Ligue 1 giants called off the deal at the last minute. United are now tracking him and sent spies to cast their eye over him in DC’s 4-0 loss to Los Angeles FC. While Acosta’s afternoon was soured by a humbling defeat, he admits he is delighted to have caught the attention of the Premier League side.

“I’m obviously happy [United] were here,” he said. “They came to see me, and obviously I just went out and tried my best. “Today wasn't my day, we were up against a great opponent and in reality I'm just sad for the group's performance today, and mine too.” United boss Ole Gunnar Solskjaer is understood to be planning a summer rebuild at Old Trafford and a new midfielder will be high on his agenda. Ander Herrera is out of contract and they will need a replacement if he moves to PSG as has been reported.

West Ham star Declan Rice remains a target while Borussia Dortmund winger Jadon Sancho is another player Solskjaer would like to bring to the club. They risk missing out on a place in next season’s Champions League after falling out of the top four having lost two of their last three games in the Premier League. However, they have an opportunity to get their season back on track when they welcome Barcelona to Old Trafford on Wednesday for the first leg of their Champions League quarter-final clash. United go into it as underdogs but Solskjaer is relishing the chance to test himself against one of the best sides in Europe again after knocking out PSG in the last 16.
