Positivity is high at Goodison Park, despite the club selling Romelu Lukaku, and Ross Barkley being deemed surplus to requirements.
The headline-grabbing move was the return of Wayne Rooney from Manchester United while Jordan Pickford, Michael Keane, Sandro Ramirez and Davy Klaassen all look like smart purchases.
Everton also have a cluster of young talent to choose from but who else could possibly come through the door as Koeman looks to turn the Toffees into genuine top four contenders?
Everton’s current first choice XI:
The big shock here is regarding Rooney who, we think, may find himself on the bench if he can’t keep up his goalscoring form.
Seamus Coleman’s horrid broken leg will require him to spend a significant amount of time on the sidelines but he could return later on this season.
Up top Sandro is unproven in the league but to grab a Spanish under-21 international of his calibre for just over £5million is a steal in today’s market.
Elsewhere Davy Klaassen will hope to be the creator in midfield and, after flip-flopping between Maarten Stekelenburg and Joel Robles last season, Everton fans will be delighted to have a certain number one goalkeeper in Pickford.
Everton’s potential first choice XI after the transfer window closes:
The big new addition is that of Gylfi Sigurdsson who’s arrival from Swansea seems to be a matter of when rather than if.
Olivier Giroud was a long time target for Koeman as well but the Frenchman appears to want to stay at Arsenal so, instead, the Everton boss is apparently targeting Danny Welbeck.
If the former Manchester United striker can stay fit he could be a valuable asset for the Toffees should he join up.
However, considering the team Everton had last season compared to this one, the club have done incredibly well in the window.
Combine the new talent with the youth and the Toffees have a squad that could really achieve something.
