Old Trafford welcomes back supporters back for the first time since March 8, 2020, although several hundred broke into the stadium earlier this month in protest at United's owners the Glazer family and their role in the failed European Super League plan.

That ugly invasion and clashes with police outside prompted the postponement of United's match against Liverpool later the same day, while there were more protests before the rearranged game on Thursday.

The return of fans to Old Trafford was surprisingly peaceful despite fears of more disruption, although many wore green and yellow scarves in the colours of United's predecessors Newton Heath, which became a symbol of protests against the Glazers when they bought the club in 2005.

Some held up signs reading "Glazers Out" and chanted against the Americans, but the discontent was drowned out by songs of praise for Cavani in the 15th minute.

Bruno Fernandes flicked David De Gea's long ball into Edinson Cavani's path and the Uruguay striker, spotting Alphonse Areola off his line, lofted a gorgeous 40-yard chip over the Fulham keeper.

De Gea was back in goal in place of Dean Henderson in what could be the Spaniard's farewell appearance at Old Trafford amid reports he could leave in the close-season.

De Gea was beaten in the 76th minute when Joe Bryan headed the equaliser from Bobby Decordova-Reid's cross.

Second-placed United, now without a win in three games, suffered another blow ahead of the Europa League final against Villarreal on May 26 when Scotland midfielder Scott McTominay limped off injured. United captain Harry Maguire is already racing to be fit for the final after suffering an ankle problem.
