For those hooked on "settled squads" [which is the cliche number 2 after "we need wingers"] it is a jolly good job Robins didn't take that view - in the case of either cliche.
It is only "settled" when it's good, but even then returning loans, the Willis sort of situation, the fact that there are always weak spots (Mason?), age (McF) mean a team is never "settled". "knowing his best team" is cliche number 3 - if the players in the squad are properly competing for places, there should always be turnover. Players always eventually lose form, particularly at this level.
So on past form, Robins will be quite active in the summer both out and in. The problem maybe that the "outs" are quite cheap, but the "ins" will be expensive.
