Scott McTominay says Manchester United reiterated the need to not get frustrated at half-time of their clash with West Ham United.

The Red Devils dominated the opening stanza but could not break the deadlock.

But an own goal from Craig Dawson shortly after the break eventually gave United all three points.

"It was a really tough match," McTominay told Sky Sports. "We know from when we played them in the cup last time, it's difficult, they've got some good players in the team, they made it hard for us at half-time.

"The message at half-time was to keep it the same, keep trying to play at the best tempo we can possibly play at, keep working the ball side to side and we'll get an opener. It came from a set-piece and it was a fortunate one as well.

"It's tough, it's not getting frustrated and that's why I'm coming off the pitch and it's not moaning, it's not shaking your head, it's not waving your arms up in the air.

"When you play against teams like that who sit in and defend well, you can't react like that, you have to play to the tempo we know we can play at. We're trying our best to keep pushing and obviously doing our best as well."
