Ajax have already proved their class by destroying and outclassing Real Madrid and Juventus, making both of them look like amateurs in the process, so they are a real force to be reckoned with. Now they are moving up to another level.
It will be a real test of their metal against Spurs, we have equally proved ourselves against a very strong City team. So it's going to be a step up against an English team for Ajax. But given their attacking ability and the excellent technical abilities of their players, they have a very good chance. They have as good a chance as any of the remaining teams, the only thing that's against them is their inexperience and the fact that they are moving up a level against the English teams, who play a much quicker pace of football.
It will be interesting to see how their world class youngsters cope against our Spurs team who are also immense when it matters. If Ajax do get past us, they will face Liverpool or the by far the best team in Spain Barcelona, both of which will be very tough games. But it is not beyond Ajax's abilities to win the CL.
That is my objective opinion, but if you want to know what I personally want, I'd love to see another exciting goal fest Spurs game against Ajax, like the one we saw today and for Spurs to reach the final. I am sure there will be more goals and that our semi final with Ajax will be another exciting game.
