Sometimes you just want to win a top league and be done with it. There are cheaper options, there are better options, but if you want a guaranteed excellent keeper for a few years, regardless of the cost. Diego Alves is the man. The Valencia top stopper has a release clause set at £21.5m, so anytime after he recovers from his long-term injury, he can be picked up by a top club in need of a reliable, top class goalkeeper. He is expensive for a 30-year-old, but he's still got plenty of time left in the tank.
