Ta Bi joined the Black Cats in the January transfer window but the 20-year-old winger was still recovering from a minor ankle problem at the time so wasn't able to go straight into full training with the squad.
But he has made good progress since his arrival and joined the first team squad out on the pitches at the Academy of Light on Tuesday morning, immediately catching the eye of Le Bris.

"He's in a good place," said Le Bris.
"He did full training this morning with contact, and he showed great qualities this morning.
"I'm happy for him because he's in a good fitness level now. And he showed good quality with his left foot."
Ta Bi joined Sunderland on a four-and-a-half year deal from Maccabi Netanya, but had been on loan at Hapoel Petah Tikva, where he'd made 12 league appearances and contributed two goals and two assists in the Israeli top flight this season.
Considering his age, lack of experience and the fact this is his first taste of football at this level, the expectation when Ta Bi arrived was that the Ivorian was very much a signing for the future.
And while that is the case, Le Bris said after the winger's arrival that he won't set any limits on what the winger can achieve on Wearside this season and wants to be "surprised" by the youngster.
Asked today whether Ta Bi can play a part this season, Le Bris said: "From now we'll see, but it's always positive to have good energy on the pitch and it was the case this morning."
