The best thing to do in Sorrento is get the bus to Amalfi. There's a really nice restaurant in a big garden near one of the old walls of Sorrento. Can't remember the name though.
The main thing I'd like Mignolet to sort out is taking the balls he comes out for cleanly. The other things are less important, and he's not quite in Lloris's class for giving the ball to the opposition 35 yards out.
