I've just never been impressed with Mahrez since he came here. He can have his moments here and there but his overall play is not suited to a Pep side that depend on the wingers in the final 3rd. Mahrez is better suited in a team like Leicester or Chelsea that defend deep ans hit teams on the counter attack. He struggles in this system where he has to shine when the opponent has 11 men behind the ball.Who does Mahrez have to pick out though? We have no striker.
Three years ago Sane and Sterling were on fire with Aguero up top and KDB pulling strings in behind. I am confident Mahrez in that team would have had better goals and assists returns than Sane and Sterling.
