Why would we? That isn't how statistical odds work. Besides which, the 1 in 10 claim is tosh, every players situation is different. If we take Sneijder as an example, from what we can gather he wants out from Ajax and wants a fresh challenge in a top league. We're in a top league, have great facillities a decent manager and lots of hard cash. Plenty of potential and ambition to boot.
Now unfortunately none of us know him personaly, so who are we to say we aren't the type of club he's looking for? Maybe in Sneijders case the chances are 1 in 5 rather than 1 in 10? How have you come up with that random number?
