Leno,Handanovic, Begovic, Hart, Butland and Fraser Forster. ETC. Goalkeeper is a must buy for us, because we are severely lacking a capable keeper.
Handanovic and Hart and the best options out of these suggestions.
Forster isn't great, I know a few Southampton season ticket holders who think he is average. Butland needs to prove himself after a long injury lay off. I don't see Begovic as an improvement on Mignolet and Leno is over-rated in my opinion, every time I watch Leverkusen in the Champions League he makes a glaring mistake that leads to them conceding!
