He was quite poor yesterday. However, both him and Van Der Vaart ( who I don't think is in the Dutch squad on this occasion ) are very talented individuals. Sadly, they haven't always paid attention to their careers. When Sneijder is focussed and fit he is formidable. He needs a disciplinarian manager to get him on track ; Van Gaal might just be that man.
Meh, don't have haven't ever rated Sneijder, he is lazy, selfish and stupid. He does the wrong thing more often than not and has had almost no good seasons.
He takes a HUGE number of shots, his last "full" season at Inter in which in the league he started 16 and subbed in to another 5 games he took 78 shots and only scored for. That is shooting more than Fabregas, iniesta, most midfielders who play twice the number of games. He only managed 4 goals from all those shots. Sneijder has for many years been propped up by a team who do all the work and let him get in shooting positions or won him freekicks he could take. 43 shots in the champs league in 9 games, scoring 3 goals, that season in 22 starts for Inter he took 107 shots and still only scored 4 goals, and had 5 whole assists. When playing a creative role, with little to no defensive responsibility, taking most if not all the freekicks. he isn't anywhere near as good as he thinks he is.
9 goals I think is his best return in any league since leaving Ajax, that was taking over 90 shots in his first season after leaving. Before leaving he scored 18 goals in 30 odd games for Ajax.... but how many people have we seen score that many in the dutch league and never come close to replicating it anywhere else.
Galatasaray is pretty much his level, and he's not doing well there either, but will be on a huge wage thanks to his (undeserved) reputation before that.
VDV I think is a better player and does a hell of a lot more for the team, but he's not a good enough scorer or crosses to take up a wide attacking of strikers position, and far far too lazy defensively to play in midfield. He's creative and will score a fair amount, there are just better players for a first team 11, better goal scorers, better crossers, better midfielders. I'd play VDV over Sneijder in the team but neither would be close to the first 11.
