Calum Chambers certainly made his mark on Sunday.
The England defender replaced Bukayo Saka at half-time following Ainsley Maitland-Niles' dismissal against Aston Villa, and got us back into the game with a clever finish past Tom Heaton.
It's the second time Chambers has been used at right back this season, following last week's win in Frankfurt. But the 24-year-old, who can also play at centre back and in central midfield, is only focused on the team.
"Wherever I am put I will give everything I’ve got," Chambers said. "As you said at the moment I am playing right-back, I played right back in the Europa League and got 45 minutes there today. It is just about giving everything I can for the team and helping where I can, and making the most of the opportunities I get.
"I spoke with Unai at the start of the season. The plan always was for me to go to Fulham, to come back and play here. That was always my plan in my head. I went away, at Fulham it was great. I had a great time there, gained some experience and have come back here and wanted to bring what I learnt last season back here and to help out the team.
"We are working every day at the training ground on our philosophy and the way we want to play. When you're down to 10 men, they are going to have chances, they are going to dominate parts of the game and that happened. Today I think it was all about spirit, digging in deep and doing anything we could to get the result - and that’s what we did.
"We've now got Rob back, we’ve got Hector coming back, Kieran is coming back. Those two played the other night. Those players are coming back and we’re looking forward to it."
