Pogba is very quick player .and he is right now way better than Kovacic .probably only here along may be Inter & Croatian forum this will be an argument .the difference in level is clear
And Pogba is perfectly fit in the LM role .he is almost playing that position with Juve also .he has all the tools minus the exceptional passes .I would take Pogba for 80-85M over Kovacic for 25M any day of the week .A club like Barcelona should always go for the special player even if we had to overpay a little and not settle for the good one .we settle we get Sanchez .we spend big we get Neymar & Suarez
That said if Pogba really goes for 85M or just sold to another club I would be ok with Kovacic .there should be a limit for what we pay as there will be a need for other signings
If we spend big we also get the special Zlatan, and if we buy smart we also get Yaya Toure.
What is important IMO is not who is considered special, but who fits our team best. I do agree that Pogba is a better player atm, but it could be Zlatan 2.0 all over again if we decide to splash big after winning the treble, and ruin the following season like we did in 2009.
