Pulis wants to build the team around 'Gards' Gardner so players like Morrison are going to be surplus, never mind in 'TP' we trust apparently.
I have been one of Gardner's biggest critics and yes, he does get too much game time, but I don't think anyone could suggest Pulis is building a team around him! Nor can he build a team around Morrison, neither are good enough.
That said, of the two, Morrison is far superior and should be kept on as a squad player. He may, of course, want to go elsewhere for regular football, in which case good luck to him.
