21:38 David Moyes walked onto the pitch at full-time to congratulate every one of his players on the victory which came courtesy of Chicharito's winner, a minute after half-time. And he was given a rousing reception by the Stretford End as he left the pitch, as were all the players.
21:34 FT: United 1 Liverpool 0. Fantastic result for the Reds who worked their socks off to get that win in what was a really enthralling cup tie. And it was great to see so many fans stay inside the stadium right until the final whistle to clap the lads off.
