Five things that we learned about Arsenal last night

A 1-0 defeat in a Champions League semi-final is a damn good result when you know that you have the home leg to come - and when you consider that Arsenal have not conceded a single goal in the competition at Emirates Stadium all season.

However, this is Manchester United we're talking about and Arsene Wenger knows that his young Guns will have to step up their game if they are going to be involved in another match at the Stadio Olimpico in Rome this campaign.

Alex Ferguson's men could have made it a more convincing margin had it not been for the heroics of Manuel Almunia as well as some excellent defending from Kolo Toure.

But it wasn't all negative for the Gunners. Here are five things us Addict editors learned from last night's trip to Old Trafford:

1. Kieran Gibbs is learning fast - will Gael Clichy be a shoe-in when he regains fitness or will the left back slot follow the Gilberto/Flamini situation last season?
2. Manuel Almunia can be world class. His goalkeeping last night was of the highest quality.
3. Manu Adebayor is a waste of space. His positioning was woeful, he is needlessly caught offside and his running off the ball to create chances was just non-existent last night.
4. Samir Nasri is wasted in big games playing deep.
5. Eduardo must start at the weekend - if he gets sharp and stays fit he could make a real difference. Bringing him on with just 10 minutes to play last night was too little too late. Adebayor should have been replaced much earlier, as his contribution was pathetic given what was at stake.
Arsenal used up all their luck last night - Ronaldo hitting the bar, Giggs was marginally ruled offside, while Silvestre headed over his own bar from a cross he knew nothing about.

But the dream of a return to Rome is still on and Arsene Wenger has five days to regroup his players and get them playing the kind of football we all know that they are capable of - and that we all know is capable of beating Manchester United.
