Manager David Moyes said he can look Manchester United’s supporters in the face again after his side’s Champions League great escape against Greek side Olympiakos. ‘In some of the games I have felt ashamed because we haven’t played well enough and I have not got a team out that has got a good enough result,’ Moyes told a news conference on Friday. ‘I think the big thing on Wednesday was that I could look at the supporters in the face after the game. ‘We had given them something to shout about. There was nothing to be ashamed of about our performance.’ United will look to build on their win over Olympiakos at West Ham United on Saturday when they will be without striker Robin Van Persie. ‘There is no guarantee that one good result will lead to another,’ Moyes said.
