The Red Devils lost 2-1, after a controversial Fabio Borini penalty proved to be the decisive goal in the first leg, held at the Stadium of Light. Nemanja Vidic had equalised for United, after Ryan Giggs deflected a cross into his own net, all from a controversial free kick.
And the Welshman was quick to comment about the two decisions, telling MUTV: “I thought both decisions were harsh. I thought the first one was a free kick to us but saying that, we still have got to defend the free kick.
“We got punished for that, but we were getting back into the game with a great header from Nemanja [Vidic] and it looked like there was only going to be one winner. We created enough chances, but unfortunately the decisions went against us.
“We did not have that little bit of luck, I hit the crossbar and Adnan hit a shot against me when I was offside. On another day that would have gone in or been given, but it just did not go for us tonight. We’ll keep plugging away and we’ll look forward to the second leg. We are still in it, and we look forward to it at Old Trafford.”
David Moyes’ men face Swansea and Chelsea in the Premier League before hosting Sunderland in the second leg, with a trip to Wembley just a game away for both teams.
