I'll love Dmytro when we swap him for a defender who actually compliments Pique, like David Luiz. I don't think it's coincidental that Pique had his worst performances as a Barcelona player next to Ukranian Jesus.
I love attack minded defenders, Pique is the future and three of my favourite all time Barcelona players are Marquez, Nadal and Koeman. The thing is all of these guys at their best were/are also brilliant defenders. Attack might separate the libero from any old defender, but it's a complimentary skill, when the only thing positive you can say about your defender is they pass well there's a problem. There's also a reason teams rarely play two great attacking CB's together. Pique and Ukranian Maxi Lopez could potentially become a better version of last years Pique--Rafa partnership, but the odds are against them because they don't compliment each other at all.
My opinion of Chyg is obviously skewed by the fact that he's replacing a Latin American and my major dislike of Ukrainian football, but lets be realistic, Marquez is nothing more than a squad player at this point in his career anyway. I just hope his successor isn't the defensive version of Maxi Lopez.
