West Ham got their Premier League points tally off the mark on Sunday with a 3-1 win over Everton.
Manuel Pellegrini was bold and changed his formation and this ultimately helped West Ham reap the rewards.
After four consecutive losses, something needed to change. And Pellegrini decided it was the formation.
The Chilean therefore switched to three in midfield, deploying a 4-3-3 system against the Toffees.
If he sticks with this formation, Jack Wilshere could be the perfect man for the role when he is back fit again.
This 4-3-3 system takes one of the attacking midfield players and places them in central midfield.
This was effective in preventing Gylfi Sigurdsson from advancing through the middle of the pitch. Instead, the midfield trio was there to block his path.
Pellegrini deployed one holding midfielder with two central midfielders operating slightly further forward.
Declan Rice sat in the deep position, while Pedro Obiang and Mark Noble filled the other two slots.
In the second half, Noble was replaced by Carlos Sanchez, with Wilshere out injured for this game.
Jack Wilshere fits the system
Wilshere sat out of the Everton clash with a sore ankle, sustained in training.
Initially thought to be minor, the former Arsenal man has had to undergo surgery and will be out for around six weeks.
If he can shake off this injury and return to full fitness, Wilshere should be a guaranteed starter in this new formation when he returns.
While he has not yet hit the heights expected of him, he has been utilised in a deeper role than he may have expected.
With Rice sitting behind him doing most of the defensive duties, Wilshere would have the license to roam forward and play a more attacking role.
He would have a front three to aim for as well. Wilshere could use his range of passes to provide service for Felipe Anderson, Marko Arnautovic and Andriy Yarmolenko.
Wilshere is looking for a route back into the England set-up and this new formation is perfect for him. This could really help to reignite his stalling career.
But more importantly, the 26-year-old is the ideal man for this role. He could fill one of the three central midfield spots in this system and get West Ham moving up the table.
