Chelsea boss Jose Mourinho is impressed by new signing Wallace.
The Brazilian fullback saw action in victory over the Singha Allstars in Thailand.
Mourinho told chelseafc.com: "Wallace is a very good player. He is mature for his age - comfortable on the ball and he likes to attack. He is not staying with us because we have Ivanovic and Azpilicueta for the same position, and also because he is not from an EU country and we need to get him a visa and it is maybe too early for the committee, so he will go on loan for one season in Europe but I think you can see the kid has talent and is another good investment by the club."
