The powerful Uruguayan missed the vast majority of last season through injury but has returned to figure regularly during the Reds' pre-season fixtures and United States tour.
With at least one more fixture to navigate in America - against AC Milan in Charlotte on Saturday - the boss was quizzed by local reporters on the future for the centre-back.
Rodgers explained: "He has done very well over pre-season. He's a player that played in the team when I first came into the club.
"He played in some of the league and European games then was out of the team. He was very unfortunate to have a bad injury that put him out for a while.
"He's done really, really well in pre-season. He's a big boy, but he can play football - he has a lovely touch, lovely technique, can pass the ball and can be aggressive.
"He's been at the club for a few years, so I think the question for Sebastian will be whether he is going to get enough games that will satisfy his own personal need, because he's a talent - there's no question about that.
"He's a real good guy as well, a humble man, he never cries about not playing. He accepts as a professional that he's not going to play in every game.
"But he has worked hard at training to get fit after his injury last season and he now looks fit. He has done well in the games and we'll see what the rest of the summer holds."
Rodgers was also questioned on his plans for the remainder of the transfer window, but refused to be drawn on specific names, numbers or positions.
"We won't have too much more business to be done, but we still have a few areas we want to strengthen," he answered.
"It's just purely on the back of us having a really thin squad last season where we were very, very short. The players did remarkably well and it was incredible what they achieved, but they need help this year - they need assistance.
"We've got the belief this year we can go on and do well in all of the competitions. Especially after the Christmas period on the back end of a World Cup year, we need to make sure we have freshness in every game we play because of the nature of our game.
"There are still one or two areas to look at. There's no point mentioning numbers or positions - we want a couple of positions strengthened and if we can do that, I'll be really, really happy."
