He left 18 months ago in a £20m deal, and Suderland can effectively preserve Premier League status if they can win at relegation-threatened Aston Villa tonight.
Jordan Henderson: "I spoke to one or two Sunderland players after they won at Newcastle and they were delighted with the result.
"I watched that game on television.
"This was also a great result for them but the main thing is it was another good result for us to win here.
"It was a great performance from the team from start to finish.
"It was important to finish the week on a high. On a personal note, I was delighted to score the two goals as well.
"I don't think we let what has happened this week (with Luis) affect us. The players have handled it brilliantly. The attention has been diverted anywhere but football this week. But we just want to get on with our job.
"Luis is a massive player for us and has scored a lot of goals this season. We're happy when he's in the side, but weve shown that we can cope when he's missing through suspension or injuries.
"I've learned this week, once again, that I'm at an incredible club. And I've learned that no matter how good a player is, you can't do what Luis did, it's as simple as that.
"He's got his punishment, we've all accepted it and we move on. As a manager, things are just thrown at you.
"When you're doing your coaching courses and you're coming through as a young coach from 20 years of age, this is not the kind of scenario you read about in the manuals.
"But as a football club we stay together. We're very strong as a club. Our supporters were brilliant at Newcastle, they recognised the intense scrutiny that was on us, so to come here and deliver that kind of performance shows the character thats in this book."
