Speaking of Torres, how is he doing in Porto? But I tend to agree with @Leo Messi, if we buy a big name and a future talent maybe we should look a bit more
He is rated very highly and if you ask the average Porto fan he will tell you that he is their most consistent performer. "Unfortunately" for him he is not as hyped as other players are. He mostly has a high star in Spain and now Portugal. Outside of those two countries not many know him.
Those of us that have followed him for years (Spanish underage national teams) will tell you that he is a very special player. In that sense he reminds me of Verratti. As soon as you saw him play you knew that you were witnessing a special player. Some players just have that "aura" about them. If you have a good eye on the game of football such players are fairly easy to spot.
I never had that feeling when I was watching Kovacic although I can see glimpses of a big talent. What I also noticed is that he is very irregular and he seems to struggle mentally when under pressure. I have never seen players like Verratti and Óliver Torres do that. Almost never. They have a natural calmness about them much like Xavi without comparing a unique player and the greatest Spanish player of all time with anyone.
Of course this thread is about Kovacic but if we bought him we won't buy another midfield talent and I honestly believe that there are better options out there in terms of young talented midfielders who are yet to establish themselves fully.
So in short.
I believe that there are better options out there than Kovacic as of now but I won't complain too much should we buy him for a reasonable price as he is definitely talented and I could see him perform well for us if he gained regular playing time and thus confidence to fully exploit his talent. BUT we should not buy him alone or as our "established midfield player" because he is nowhere close to that.
That's why my ideal pick is us buying Pogba and Óliver Torres. I would have chosen Verratti but I won't mention him as he is not realistic for us unfortunately as he would be the best pick out there.
