Michael Carrick insists Manchester United Football Club are over their blip.

A 1-0 win at Porto booked a place in the UEFA Champions League semi-final on Wednesday night, and put an end to a string of less than convincing performances of late including two Premier League defeats.

"When you have a couple of bad results people start questioning you," said Carrick.

"But we have always known what we are capable of and last night we got back to what we do best. We defended well as a team and looked really solid. All of a sudden everything looks great again."
