United have a mountain to climb now

Manchester United's hold on the Champions League hangs by a thread after Porto left Old Trafford with a well-deserved draw - and two crucial away goals - on a disappointing night for Sir Alex Ferguson's side.United now had the task of going to Porto and winning the game which no English teams had done . They gave away two away goals very easily . Defensively it looks like United have got a lot of problems . Except for Vidic and Van der sar they looks shattered defensively and Ronaldo the recently titled world footballer of year looks like he is not interested at all on what is going on ground .Giving away ball cheaply and not even trying to win it back it looks like he wants to play for Real .

The only player who tried to do something for United is Wayne Rooney . But the United forward has not got enough support from his team mates . The United players were very tired as they are playing only 48 hours after their last game and recent international duties .

Christian Rodriguez gave Porto the lead inside four minutes, his sharp finish coming as a result of the defensive uncertainty that plagued United from start to finish.And even though Wayne Rooney swiftly levelled after he swooped on Bruno Alves' backpass, there was to be no escape for United. United gave away possession at will and displayed the sort of alarming defensive vulnerability that was first exposed in the home defeat against Liverpool.

Throw in a disjointed midfield and an attacking effort that relied almost solely on the inspirational Rooney, and all the ingredients were in place for the visitors to produce a shock.Porto, in contrast, were sharp on the ball and bright in attack - encouraged by the inability of their opponents to apply any concerted pressure on their defence.

Carlos Tevez's strike five minutes from time looked to have given United an advantage they barely merited as they looked a pale shadow of a side on course to collect an historic haul of five trophies.But as Old Trafford breathed a sigh of relief, Porto delivered what could turn out to be the telling blow when Mariano scrambled home a last-minute equaliser to rekindle dark memories of United's exit to the same team five years ago.
