Arsenal found themselves 2-0 down against Leicester City, with a mere 14 minutes left of the game.

In an attempt to get back into the match, Unai Emery opted to bring Nicolas Pepe on for Rob Holding, changing the formation from the 3-5-2 that had been deployed from the start of Saturday's evening clash.

And a number of Arsenal fans reacted angrily to the substitution, for a variety of reasons. Some were left wondering why the manager took so long to make it, others asked why the Ivorian wasn't starting in the first place and a few seemed to have quite simply run out of patience with the manager.

The confusion around the decision to not start the summer signing and then bring him on so late is only enhanced by the fact Pepe has begun showing signs of good form recently, having got two goals and an assist in the two Europa League games against Vitoria de Guimaraes.

The 24-year-old was able to muster up 2 dribbles while on the pitch, but couldn't manage to produce any key passes or shots, giving an indication of how limited he was by the time constraints.
