2. David Ospina
Petr Cech will not be going for much longer. By the end of the season, he will be 36. That does not necessarily mean that he needs to be replaced this summer. While his performances have tailed off recently, they are not at the disastrous level yet to require such immediate action. But it is perhaps time to think about a succession plan.
One man who should definitely not be a part of that succession plan is David Ospina. The Colombian international, who will be 30 when next season commences and has likely reached the peak of his potential, has showed a great number of major shortcomings, from lapses in concentration to a lack of size and stature, from a failure to command his penalty area to his rash, complacent, and oftentimes utterly puzzling decision-making.
It would be wise to perhaps bring in a younger goalkeeper to take on the reserve role that Ospina is currently fulfilling, with the intention that he will succeed Cech in a year or two. Ospina is caught in the middle. He is neither a prospective youngster nor a reliable long-term option. For that reason, it is time to sell and move on.
