I think if we can hold onto our big name players (Suarez and Agger) and quietly add another striker, a center back, competition at GK, and a midfielder, then the summer will be a success.
Reina is a tricky one. I'd keep him unless someone comes in with a stupid bid (over 10m) while adding at least one talented backup keeper (Brad Jones is bobbins-nowhere near good enough to be out backup).
