Isn't Mendy quite prone to the odd niggling injury? Seems to be one for picking them up quite frequently. Some players just are. This is why it's such a huge risk going with just 3 players for 2 positions. 1 injury and you're down to the bare bones, it makes us more predictable to the opposition and leaves no chance to rotate or rest which is crucial in the most physically demanding position on the pitch. If we're relying on Fernandinho as cover it's going to cost us dearly as he very clearly is not a fullback and despite giving his all gets ripped apart every single time he plays there. If it's a money issue and a choice between a fullback and a new centre half then I'd much much rather see Mangala at centre half than Fernandinho at fullback.
