Foresight is valuable and if Unai Emery had any indication he would be managing Arsenal this coming season he may well have made some different decisions in January.

BBC Sport reported this week that Emery will replace Arsene Wenger as manager of the Gunners, surprising most who had expected Mikel Arteta to be handed the role.

Emery will quickly come to learn about the fierce rivalry Arsenal enjoy with Tottenham, and finishing above Spurs in his first season would go down as a success.

Unfortunately he made his task harder with his decisions over the past year.

Emery forced winger Lucas Moura out of Paris Saint-Germain, deciding not to play him despite the Brazilian scoring 19 goals under him in 2016/17.

The arrivals of Neymar and Kylian Mbappe pushed Lucas Moura aside, and he was selected by Emery for only five Ligue 1 matches before he sold him in January... to Tottenham Hotspur.

Arriving mid-season, Lucas Moura is only just getting started at Spurs and has impressed in his limited appearances so far.

Next year Lucas will have an extra point to prove to his former boss Emery in the North London derby matches, and the new Arsenal manager has to hope his decision to sell to Spurs does not backfire.
