Callejon isn't all that, he'll have to fight for his place, and Reina is only a loan, besides I don't think he's that good anymore which is why Liverpool are trying to get rid. They've gone for Madrid rejects and a player who's unwanted at Liverpool, I prefer how Dortmund used their Götze money to replace him with Aubameyang (one of the best forwards in France and a potential Lewandowski replacement) and Mkhitaryan (very highly rated and young).
