Maresca facing huge decision on Chelsea signing Anselmino

The young defender completed a £15.6m transfer to Chelsea in August but immediately returned to Boca Juniors on a loan deal. He has now arrived in West London and will join training with Enzo Maresca's team from next week.

Maresca will consider whether the 19-year-old, who has signed a seven-year contract at Stamford Bridge, can automatically earn a place in his backline due to the club's current injury crisis.

Argentine legend Juan Roman Riquelme and Boca president told ESPN: "He has developed a lot. With the growth, the head that he has and the desire to learn that he shows, he is on his way to being a great footballer.

"He is going to be a player for the national team. He is going to compete with the centre-backs."
