Arsenal boss Mikel Arteta has explained playing Martin Odegaard in a deeper midfield role.
Odegaard has recaptured his best form playing closer to the back four.
Arteta explained ahead of tonight's clash with West Ham: "Well there are certain games that require certain things from certain players.
"We have used Martin to accommodate the needs of the team to make us better against certain behaviours and challenges that the opponents put for us. That's a big quality of his.
"He also the defensive part which I'm really impressed with and I'm really happy with that because it's a part of the game that we want to transform and keep evolving."
