The demolition of world champions Spain at the hands of the Netherlands on Friday night taught us many things. Even a golden era for a team has to falter at some point, Robin van Persie clearly has a great relationship with his future club manager and anything can happen at a World Cup.
Another thing that we learnt was that on his day, Arjen Robben is one of the most destructive players in world football. His performance against Spain was one that will be spoken about for some time, especially if the Netherlands go far in this tournament.
The Bayern Munich winger is a constant threat and always wants the ball, which is a dangerous combination. The fact that he plays on the right and then cuts in on his favoured left foot make him a constant goal threat - even though defenders know he is going to do it - because his close ball control is exceptional.
This is the one area in which I would say he is definitely better than current Ballon d'Or holder Cristiano Ronaldo.
The main threat, however, has to be his incredible speed, despite the fact that he is now 30-years-old. Granted this is not old, but a winger's speed normally drops in their late 20s and this does not appear to have happened for the former Chelsea man.
The manner in which he left the Spanish defence for dead for his second goal, regardless of giving them a five-yard headstart, was out of this world. It is truly electrifying when he runs flat out and I am sure there are not many players who would be able to catch him.
Robben has played for some of the biggest clubs in the world and enjoyed a great deal of success but it has only been since his move to Bayern Munich in August 2009 that he has truly hit the heights of being one of the best.
His consistency has dramatically improved and the style of play adopted by the German champions has clearly allowed him to embrace a more attacking role. His goal tally has been in double figures every year at Bayern, a feat he failed to achieve in his time at both Chelsea and Real Madrid.
Robben has always seemed to be a very competitive player, but I have to admit that I was not a massive fan of his during his time at Chelsea. I felt that he had a bad attitude toward the game and would often go down far too easily.
In a similar fashion to Luis Suarez when he was universally hated in England, it was frustrating as he clearly had unlimited potential but was failing to harness it.
I am happy now, however, to hold my hands up and say that he has become one of the most exciting players to watch in any league and at Bayern, he is a standout player in the most impressive club squad since 'that' Barcelona team.
When he picks up the ball and runs at a defender, you know something is going to happen and that makes for very entertaining football.
I feel that as much as he has had a lot of success at some big clubs, Robben is now at his peak as a player, and he doesn't seem to be slowing down. Don't be surprised if he continues to take this World Cup by storm.
