Our pocket dynamo from the Ukraine marked his return to first team action with a goal in our Worthington Cup win at Fulham last week.
He was back in the starting line-up for Monday's thriller against Bolton and with Les Ferdinand struggling to overcome an ankle injury, he looks likely to partner Teddy Sheringham again at Charlton on Saturday.
Sergei reflected: "I didn't play for a very long time and in my first game back I scored a goal. Of course, this gave me cofidence and I feel confident now.
"I'm playing in a good team, a great team, but now we are playing football.
"I like playing the passing game. I'm used to it. When I played for Dynamo (Kiev) we always played the passing game, never the long ball. I see now we pass and move and it is great football."
The 27-year-old said we learned valuable lessons in the 5-3 defeat against Manchester United and since then, with a new-found ability to win away, we have gone from strength to strength.
Sergei recalled: "We lost at home to Chelsea and Manchester United but we played brilliantly, especially in the first half - I've never seen this against United before!
"The second half went wrong. It was a lesson.
"We now win away a lot of times and, of course, we can play in Europe.
"We have a good chance in the Worthington Cup, FA Cup, I hope so. We should definitely play in Europe next season if we can continue the football we are playing now."
The Valley holds good memories for Sergei after he scored in last season's thrilling 4-2 FA Cup victory. We were 2-0 down before an own goal, Darren Anderton, Oyvind Leonhardsen and Sergei's strike sent us into the quarter-finals.
"In English football you can always change things," he added. "I remember the first half, we were 1-0 down, played not so good but when we started the second half we were brilliant.
"We scored a couple of goals and the confidence grew. It was the same against Bolton on Monday.
"After the first half we scored straight away at the start of the second half, another two, three minutes later and we are full of confidence. If we start well at Charlton we can win this game."
Sergei Rebrov has his shooting boots on again - and he's hoping to fire us towards European football next season.
