#5 Nicolas N’Koulou – Lyon
On paper, this move looked like a steal. Nicolas N’Koulou was highly rated by a number of clubs across Europe for several years as he continuously impressed at Marseille, yet Lyon managed to snap him up on a free transfer.
That is about where the success story ends. The Cameroon international missed almost six months of action out of the squad and because of the Africa Cup of Nations but alongside fellow disappointment Mapou Yanga-Mbiwa, he was a catastrophe in a leaky back line that cost Lyon their place in the Champions League.
In fact, it’s that bad that reports are already emerging that the club are ready to sell him after just a season. What looked like a move in the right direction for Jean-Michel Aulas’ club has only helped sink them further down the pecking order in Ligue 1 which could get worse this summer.
