Intl comp is a totally diff beast with all to play for. Footballers tend to approach it differently. I wouldn't dwell too much on their club form because there is no guarantee they can translate their superior weekly showing on the Intl stage. Conversely, Barca players came trumps in the summer of '08, at the back of a disappointing season. As long as key players can make it without any kind of fatigue wearing them down, I'm not worried how they finish the season with their respective clubs.
Though, liabilities like Romero continuing to showcase their incompetence is disconcerting. This from the recent cup match. He's slightly better for the Skyblue, but that's not a consolation.
Agüero should be fine by the time summer arrives. And its not fair to compare Pipita's stats with llorente, who has a much superior supporting cast at his disposal. Napoli don't tend to create much, and their MF/WF always prefer to shoot rather make a pass to their frontman. A lot of the times they don't even pick Gonzo's runs. Their only decent creative player in Hamsik was out for nearly 2 months. Additionally, at Napoli his role is that of as a target man, dropping in to MF, and bringing others in to play. He's Napoli's leading assist-man over all competitions. When given a good supply, he'll cause damage as he always does. Shouldn't be a prob with Arg. As for Gago, the latest reports confirm he should be back in time for their last warm-up against Slovenia. If not Banega should step-up. (I hope)
