Chelsea forward Lucas Piazon says he is helping new signing Wallace settle into the Blues’ squad.
The 19-year-old moved to Stamford Bridge this summer from Brazilian side Fluminense, having already signed a pre-contract with the club in January.
And after flying out to Bangkok on Friday to join the Chelsea team, Wallace has been helped to acclimatise by Piazon and fellow Brazilian Ramires as he looks to ease any early nerves.
"I played with Wallace a lot before, in the Brazil Under-15 and Under-17 teams, and he is a quick right-back who likes to attack a lot, but he also defends very well as well and I am sure he will like it at Chelsea,” Piazon told the club's official website.
And, having returned from a loan with Malaga in Spain last season, Piazon, also 19, is happy with how pre-season has gone so far.
"Training has been good, very hard, and some of the players are very tired, but that's pre-season, and we're all enjoying it," he said.
"I think the heat is easier for me because I am used to it in Brazil like this.
"I also think it was good for me [to go on loan]. I could play a lot of games and played in La Liga, the Champions League and the Copa Del Rey. It was nice to finish the season playing some important games so I was happy."
