Owen Hargreaves has virtually written off his chances of making his Champions League debut for Manchester United in Lisbon on Wednesday.

The 26-year-old pulled out of the recent England double-header with a thigh strain and also sat out Saturday's Premier League win at Everton.

However, Sir Alex Ferguson was optimistic Hargreaves would be fit for the trip to Portugal, when United begin their quest to better last season's semi-final appearance.

Hargreaves was unable to train this morning and now appears resigned to setting his sights on the weekend game with Chelsea instead.

"It's okay, I have never really had this injury before so this is new territory," said the midfielder. "I thought I would be fit for the Israel game, then the Russia game and then Everton, but I've still not done it. I have to take it day by day so hopefully I will be fit for the weekend.

"I can't say for certain but it looks as though I won't be ready for Wednesday because I have not trained."

Hargreaves believes this latest injury, allied to the tendinitis problem which effectively scuppered his pre-season programme and ruled him out of the opening two games against Reading and Portsmouth, is a legacy of the broken leg he suffered in Germany 12 months ago.

"It is frustrating," he said. "I missed pre-season then I had a run of games and I was really enjoying it.

"It is just disappointing to suffer something so niggly. But I think these injuries come from last season when I broke my leg."

His absence will be a blow to Ferguson, who already has a long injury list. Mikael Silvestre was ruled out for the season after suffering cruciate ligament damage at Goodison Park. Park Ji Sung and Ben Foster are currently recovering from similar injuries.

Wayne Rooney is hopeful of being involved in Lisbon after fracturing his foot on the opening day of the season, but midfield duo John O'Shea and Darren Fletcher are definitely out after suffering knee injuries on international duty with the Republic of Ireland and Scotland last week.
