Speaking to the media, Guardiola said: "He can become a good right-back for the physicality. I think he's not a player to play in the middle because he's not clever enough, in composure. He has incredible skills and he's learning a lot; full-backs always have a big mistake when a cross to the far-post where you are, always they're sleeping.
"He defended really well two or three crosses from Bruno Fernandes, [Patrick] Dorgu. He has physicality to do it, he can play that position and he's helped a lot. When we started the season and I tell we're going to play Matheus at right-back, Nico [O'Reilly] left-back, you'd tell me, 'What are you talking about?' But the season is what it is."
