But he should stay here for a couple of years at least and see if the club developes properly in that time. Then we will hopefully be in a better position and could more easily attract a proper replacement if he leaves.
Would be a very bad decision to sell him after this season. At least have him for next season and sign proper fullbacks and a centre defender for the first eleven. Sign Soucek and increase the depth in midfield and attack and challenge for Europe !
