Whykwould they be competing for one spot? Llorente and lisandro can easily play together. Lopez has experience playIng the wing which means he is comfortable coming back to gt the play running at defenders and taking them on/creating providing etc. he may not be as technical but more effective in terms of scoring. Llorente has two good feed strong to hold off the defender and comfortable with coming deep in midfield to receive balls to open up channels behind him for our channel runners marchisio etc. lisandro being out through on a run behind the defence is a lot better then Vucinic. I see I reason why they cannot play together.
Our playmaker is in front of the defence, marchisio and vidal making forward runs.
On top of that, Llorente brings us a deep targetman, that can play with back to goal.
What this creates is a whole lotta space for midfield runners to move in, and for the supporting striker to be creative in.
If you take lissandro as supportive striker, he's by no means the connection vucinic is, and not nearly as creative. Instead he'll take up running space from vidal and marchisio, and cannot benefit from his finishing playing so close to midfield.
Vucinic on the other hand, now sees a diffrent player taking the targetting role aswel, giving our players options who to target, and him more space to move into. it will benefit his creativity and scoring.
Also giovinco, could use all that space llorente creates quite good, or could pair lissandro in a more counterattacking style
Lissandro, could also play at Llorente's spot, for a diffrent kind of attack, paired with vucinic or giovinco.
But lissandro+Llorente, would nullify a bit of llorente's work, imo.
Vucinic,giovinco and Llorente, lissandro, would be quite a good attack.
