I already answered you earlier. Can't believe you're continuing this.Why did Marquinhos spend all his time around the first team instead of training with the academy?
This is a rhetorical question btw.
Marquinhos, however, is regarded as a development player and will not be a barrier to other first-team acquisitions.
Technical director Edu said: “We’re delighted to have completed the transfer with Sao Paulo, as Marquinhos was a player we had been watching for a while. At 19, he is still very young, so he is a player for the future. We look forward to Marquinhos now joining us for pre-season, making his new home, and continuing to grow and develop with us.”
