I reject your reality, I substitute my own !!
Marquinhos cost 3,5 million euros, and has only experience in Brazilian league, and not even much of that. An opportunistic signing for cheap.I mean we’ve literally just bought a 19-21yr old project in attack, there really is no need for another one
He is not something to depend on this season imo. A loan would be good, but I think they want him to adjust to England, Arsenal and the tactics etc. first, and likely loan him out in January.
He should be not in these conversations. Pino for example already has experience from winning UEL, games in UCL, has played for Spain and a season in the 2nd toughest league in the world.
