Erik ten Hag hails Alejandro Garnacho for 'downsizing' Southampton as substitute helps fire Man Utd to much-needed win

Garnacho was benched against Southampton but came on in the second half and had a serious impact. Firstly, he was fouled by Stephens, with his knee-high challenge being met with short shrift by the referee and resulting in a red card. Then, in injury-time, he scored his side's third goal.

Garnacho started against Liverpool but has been on the bench for all of United's other three fixtures. And his manager was delighted to see the impact the winger had from the bench, using his performance as a way to implore future substitutes to adopt the same attitude.

Ten Hag told United's official website: “I think we should have scored earlier on, we had the chances and we had the control, and we create some good chances to score the third goal earlier on.

“Of course, we are happy when you bring a sub on who has an impact and he (Garnacho) was the one who downsized the opponent to 10 with a good action and then a good finish.

“I think also the rest (of Garnacho’s performance), I was happy with this sub and that is how players should act from the bench and we need more of this.”

Garnacho will hope to play a role in Tuesday's Carabao Cup tie against Barnsley at Old Trafford. They then return to Premier League action against Crystal Palace at Selhurst Park next weekend.
