Manchester United midfielder Darren Fletcher insists they can still eliminate Porto from the Champions League, despite last night's 2-2 draw.

"The performance could have been better," Fletcher told MUTV. "It's an uphill task now, but one we're definitely capable of. At least we know what we have to now in Porto: we've got to go there and win."

Earlier in the match, the visitors had taken the lead after just four minutes. The Portuguese champions then continued to press and carved out half-a-dozen good chances.

"They're one of the best teams we've played this season," Fletcher said. "Their front three are all very dangerous, powerful players.

"They like to play on the counter-attack, which we will have to be wary of when we go out there. We know exactly what we're up against now - the challenge has been set and it's up to us to be equal to it.

"A draw at home in the Champions League isn't a great result, but it's not a disaster. It's still all to play for."

He added: "We can't be too cavalier away from home," Fletcher warns. "We'll have to take our chances when they come and make sure we don't concede at the other end. We'll give it our best shot, don't worry about that. All the lads are up for it."
