He should be sold because he's got some market value and very little contribution to our case. Padoin is more reliable. Isla gets beaten by freaking Constant and De Silvestri (Viola reject) while Padoin kept it up nicely with Ribery in CL. Both have nerly to zero contribution in offense but Padoin is better defensively.
Sell and spend it on some proper winger. Cuadrado would be great
