All three players have signed contracts which will ensure they remain part of manager Mark Hughes' plans for the immediate future.

The trio have agreed deals which will keep that at Ewood Park until the summer of 2012.

Warnock, 26, admitted the contract was a ringing endorsement of a positive start to his Rovers career.

He told the club's official website: "It is fantastic, I think the club offering me a new deal is reward for what I've been doing and obviously I've been doing something right.

"It is a massive thing to be offered a new contract and when you see how the club is progressing and how things are going then you want to be part of that, and things are going well so I can't really argue."

Warnock, who joined for Liverpool in January 2007, suffered a stop-start career at Anfield but has been a virtual ever-present under Hughes.

He added: "I played a full season while I was on loan at Coventry and I kept myself fit and I think that is what happens when you are playing week in, week out. You seem to keep fitness a lot better and stay away from injuries.

"When I was at Liverpool I was in and out of the squad and in and out of the team and it was hard to take because you think you are good enough to play, but coming here the manager has given me a great opportunity and I like to think I've taken it."

Olsson, 19, who joined Rovers just over two years ago from Swedish side Hogaborgs BK, was pleased to agree a new deal and is keen to make a first-team breakthrough next season after making his second Premier League appearance as a substitute in the 3-1 win over Derby at the weekend.

"I'm very happy to have signed a new deal, it is what I've been working hard for, to get a contract with the first team," Olsson said.

"I've been doing well, I've been working hard, I came here two years ago and now I'm delighted to get that first-team contract.

"I've been in the squad a lot of times and on the bench too in some games, so my aim for next season is to be more involved and play more first-team games.

"I'm learning all the time in training and I'm delighted that the manager has shown this faith in me."
