Lallana at this point in time IS the better player no doubt.
His actual footballing ability is very very good and his consistency is incredible. This is why we are after him. He does suit our system almost perfectly.
Where i agree you is that he almost seems a luxury player for us right now in that we could be tackling the CM spot more heavily e.g fabregas, kroos, martinez etc and this would help us a lot more moving forward, and for the balance of the team.
Based on what?
How much better?
In which respects?
How much value would you place on the improvements you believe he would provide?
How much value would you place on the loss of Coutinho's input?
Is the net improvement you calculate worth say £25m for what's likely to be no more than 4 years' contribution?
