Chelsea are heading back to Wembley to meet Arsenal on Saturday week – meaning those two London clubs will have won nine of the first 14 FA Cup finals to be held at this version of the national stadium.

But this was a victory served up to them on a plate by Manchester United boss Solskjaer and keeper De Gea – not that you’d fancy the Spaniard to serve anything up on a plate without spilling it just now.

De Gea made shocking errors to gift goals to Olivier Giroud and Mason Mount either side of half-time.

And he might also have prevented a Harry Maguire own goal for Chelsea’s third as United’s 19-match unbeaten run was toasted by Frank Lampard’s team.

But Solskjaer’s weirdly defensive team selection had already handed the initiative to Chelsea.

Anthony Martial, Paul Pogba and Mason Greenwood were all benched as Solskjaer opted for five at the back and two holding midfielders.

Belt, braces, another belt. But a bloody great hole in the seat of his pants, courtesy of De Gea.

The one change Solskjaer had been expected to make – but didn’t – proving the worst selection of all.

Sergio Romero has been the Norwegian’s Cup keeper all season but here he opted for De Gea and saw that decision back-fire explosively.
