Suppose we leave Kolarov out and he starts the PL games either side of a CL tie- does that really affect us? Similar with say leaving Jovetic and Negredo out.
It only becomes an issue if we have injuries concentrated in our CL registered players in which case things could get messy and it's over to the youth team.
Let's say we leave Kolarov out and he wants out because he is at the club to participate in CL, do you not think this would cause problems in the dressing room?
