Ole Gunnar Solskjaer was pleased with his players’ attitude and focus as Manchester United progressed to the FA Cup quarter-finals with an extra-time win against West Ham.

Having seen victory ripped from their grasp with the last kick of the ball on Saturday, the Red Devils produced a positive response to that frustrating 3-3 Premier League draw against Everton.

United had to dig deep against former manager David Moyes’ in-form West Ham side, with substitute Scott McTominay meeting Marcus Rashford’s fine lay-off with a thumping strike to secure a 1-0 victory in extra time.

West Ham defender Angelo Ogbonna was forced off early into the match and his replacement Issa Diop was withdrawn at half-time, becoming the first concussion substitute in English football.

The defender was taken off having clashed heads with Anthony Martial towards the end of the first half, with the Hammers also losing Andriy Yarmolenko to injury early in the second period.

“We think (Diop) is fine and I still think he’s fine,” Moyes said.

“But he had a bump on the head at half-time, so I chose to take no risks and I took him off.

“(Ogbonna) had an ankle injury and Yarmolenko looks like he’s opened up his knee ligaments a little bit, so we need to see how they are. They’ll have tests tomorrow.

“Hopefully they won’t be too bad but I think we’ve seen a little bit of a rise in injuries over the last few weeks.”
