MANCHESTER UNITED fans were left fuming after Diogo Dalot went off injured against Charlton. The Carabao quarter-final clash had been going to plan after Antony’s stunning opener. 2Medical staff assessed Dalot after he went down with a knockCredit: Getty 2The full-back was replaced by Aaron Wan-Bissaka after walking offCredit: PA But then Dalot was subbed off after picking up a knock just after the half-hour mark with Aaron Wan-Bissaka on his place. The 23-year-old is the club’s first choice right-back and now could potentially miss Saturday’s huge Manchester Derby. Some fans may have been surprised the full-back was starting the cup clash against League 1 Charlton, which Manchester United won 3-0. Other first-team stars like Marcus Rashford and Bruno Fernandes had been removed from the starting line-up ahead of the weekend game, but Dalot was looking to build match fitness after a recent knock. The injury left United fans both fearful and annoyed. One panicked supporter tweeted: “Dalot injured in such a bad time! Too many matches to play.. Already vdb [Donny van de Beek] injured for long term!” Another United follower said: “Dalot injured ffs. Need a right-back asap. I still don’t think we’ll get top 4 due to our lack of depth.” While a third fan said: “Dalot’s injured? I ain’t watching.” Most read in Football FREE BETS AND SIGN UP DEALS – BEST NEW CUSTOMER OFFERS And another complained: “Dalot injured. Honestly can’t catch a break with injuries this season man. City on weekend and we’re going to have to play [Wan-Bissaka].” Many fans also took note of the fact that after City, the Red Devils have difficult games against Crystal Palace and Arsenal to come. But not all fans from the red half of Manchester were doom and gloom. One said: “Dalot isn’t injured, Erik ten Hag just isn’t taking any chances.” If Dalot can not make the game against Manchester City, it is possible Wan-Bissaka may deputise in his absence. While the former Crystal Palace defender has been out of favour under ten Hag, he has started in all of United’s post- World Cup league games while Dalot recovered from a previous injury. He has been linked with a return to Selhurst Park this month.
