i wouldn't save it and run two games, i prefer to stick to any decision i make, what ever it is!
Just out of interest, is Bertrand absolutely killing it for you at LB?
When I was playing my Chelsea game, I got Bertrand back from loan, and had him in the squad immediately, and he started to skyrocket in value, and earnt some England caps too...all in the first season and a bit.
I stopped playing that game till the new patch, where I will start another though.
Oh, and on the question...stay where you are.
