Manchester United fans have slammed Marcus Rashford for his disappointing display against Southampton on Saturday (August 28) at the Saint Mary's Stadium. The Englishman was once again deployed as a No. 9 this weekend thanks to his impressive performance against Liverpool on August 22. However, the forward failed to recreate his performance against the Reds, which left the club's supporters infuriated.Rashford endured a dismal 2021-22 campaign during which he scored just five goals in 32 appearances in all competitions. The forward also lost his place to Anthony Elanga in the second half of the campaign. The England international has been given the chance to rejuvenate his career by new Manchester United manager Erik ten Hag. The forward came into the 2022-23 campaign on the back of an impressive pre-season, which gave United fans hope that he would return to his best. After disappointing displays in the club's opening two games, Rashford burst into life against Liverpool at Old Trafford. He capped off an impressive performance by scoring in the second half.However, Rashford was largely anonymous against Southampton. He struggled to make an impact in the final third and was criticized by Manchester United fans for his attitude and work rate.Here are some of the reactions: Depressed Man United Fan@MUFC_SB@markgoldbridge Rashford is a ghost as a lone striker???
