So when Arsenal travel to West Ham United at Saturday lunchtime with almost a completely fit squad, bar those that are already done for the year and the odd player here and there, it will be extremely interesting to see what Emery’s team selection will be. In fact, I might go as far as to say that the XI he picks for West Ham could be the most interesting one of the whole season to date.

What formation will he choose? A back three or a back four? Will he select a midfield diamond, a central pair, or a 4-3-3 with two proper wingers? Do both Alexandre Lacazette and Pierre-Emerick start? Who is the number one left-back? What pair does he trust the most at centre-half? These are just some of the questions to which answers will be slightly unveiled on Saturday.
