Per Mertesacker feels Arsenal teammate Danny Welbeck is a little bit down after knocking Manchester United out of the FA Cup.
The England striker scored a 61st-minute winner to help guide the Gunners to a 2-1 triumph over his former club in the quarter-final of the famous cup competition at Old Trafford on Monday night.
After the match, Mertesacker told the BBC that perhaps Welbeck felt a little guilty for sending his boyhood club crashing out of the cup.
"Danny Welbeck was a great player here at United, he's a bit quiet in the dressing room at the moment," the German centre-back said.
"I think it hurts him a bit as well as he was here for a long time.
"We tried to get him going and to tell him he can enjoy special moments with Arsenal."
