ATM the talk seems to be on wanting 5 signings this summer = GK, LB, RB, CM & AM.
Whilst there is an obvious need for each either in terms of numbers and/or quality, IMO we have an equally if not more important issue in our attack and at CF in particular. It's plain as day we aren't scoring enough goals (we're 9th re GF), so if we're not changing our resources then our playing style then must do so, as retaining the status quo in both areas will not be good enough.
IMO one or both of PEA / Laca needs to be replaced by a CF better suited to the role required in 'Artetaball', the only caveat being if we change the style and patterns in the final 3rd.
