It's a shame this game isn't the final, but at least we get to see these teams match up twice.
On form you'd bet on United, but one look at Barca's forward five is enough to keep your money in your pocket. Eto'o, Messi, Henry, Xavi and Iniesta - not many weaknesses there. Oh and on the bench new wunderkind Bojan. ManU may be the better unit, but Barca have the better individuals. Barca don't have the strongest defence, but in the past few games Utd's has hardly been rock solid. ManU have the advantage of playing the second leg at home, but Barca will be resting players at the weekend while the Mancs will be battling against Chelsea. So like Clinton and Obama, it's pretty even.
Ironically, Barca's best tactic could ultimately help United. Barca have to go on the offensive, and hope that by doing so they regain a bit of self belief and unity. If they do, any opponent is going to suffer. But if their attack is disjointed and unconvincing, as it has been over the few past months, they could leave themselves open to the counter, Utd's strength.
There's an argument that of all the teams Man Utd deserve to be in the final, as they've played the best soccer this year. But Barca going through would mean a final without two teams from the same country. I think Barca might sneak it. Utd have looked a bit shaky over the past couple of weeks, especially against Arsenal. Messi will frighten the crap out of them, Henry will see the Utd shirts and remember that he's a top player, and Utd will fuck it up at the semi-final stage again. Perhaps.
Check back for an update, later in the day.
