Now they must know what it's like for the majority of the Premier League whenthey are passed to death and chase shadows for 90 minutes.
TOTAL COMEBACKBut we saw the other side of Arsenal. The character in their comeback was something else.
And Cesc Fabregas, suspended for the second leg, was their leader.
He played like a warrior and then sacrificed himself for his team, staying on when he was injured. What a player!
Missing men: Puyol will not feature in the return leg after he was sent off for bringing down Fabregas, who fears he has broken his leg after scoring
MEN AT WORKPeople who watch Barcelona tend to overlook one of their strongest qualities hardwork to win back the ball.
The pressure they place you under forces errors. They went hunting in numbers all over the pitch, denying space and pressing the ball. Impressive.
TEARS FOR A STARFabregas' ban is not only crucial but a shame. You want the best players on the biggest stage.
Who will miss their banned stars the most?
Barca have the heart ripped out of their back four. Puyol looks like a mini tarzan and they will feel the loss of their king of the jungle.
Missing link: When Ibrahimovic went off, Barcelona were not as potent in attack
MISSING IBRAZlatan Ibrahimovic is an enigma who reminds me of Eric Cantona.
It was his night and Barcelona lost their way when he went off. It showed the human side of Pep Guardiola: why did he send on Thierry Henry for a 'friends reunited' tour of the stadium? It was costly.
PACE IS ACETheo Walcott booked his World Cup place with that cameo appearance from the bench that suddenly rattled Barcelona's back four, who were in cruise control.
They soon had to liven up! He was dynamic and direct.
And it was nice to see an Englishman on the pitch!
