Pepe Reina.

Pepe Reina is one of those few players for whom age is just a number. He is one of the best goalkeepers of this generation who bossed at Villarreal & Liverpool in his young age, then joined Napoli aged 32 and gave top class performances for next 3 seasons. Now he joined Milan and attracted attention in his first game with a top class performance. He would be 36 next month but he still has like 2-3 good seasons remaining in his career. Even if he joins Chelsea this season, Chelsea would get a solid goalkeeper for next few seasons. If he stays at Milan young Donnarumma & Plizzari will have a great mentor to learn from. Reina is one from the category of Ronaldo, Buffon etc for whom age is just a number.

Kinda foolish from Liverpool to let go of Reina in his early 30s to settle for mediocres like Mignolet & Karius for all these years.
