#4 Layvin Kurzawa
Did anyone really notice how much of an impact Lionel Messi had on the PSG vs Barcelona game the other night? Fielded out on the right-hand side, the Argentine was constantly tormented by defenders, with one in particular, Layvin Kurzawa, proving to be a thorn in his side.
On the other hand, did you notice Arjen Robben's incredible goal, Douglas Costa's cross for Robert Lewandowski and the ball that was fed into Thomas Muller to make it 5-1? All those deliveries came from the right-hand side of the pitch – an area of the pitch Kieran Gibbs was supposed to be taking care of.
Nacho Monreal and the Englishman are both past their prime and Arsenal need someone in the mould of Kurzawa to come in and enforce a level of dominance we saw from the likes of Ashley Cole in the past. It's about time. No more excuses and no more chances.
Player(s) to replace: Nacho Monreal and Kieran Gibbs
