QPR boss Neil Warnock believes the best is yet to come from Alejandro Faurlin after he signed a two-year contract extension on Tuesday.
The Argentinian playmaker cost the R's a club-record £3.5million when joining on a three-year deal from Instituto last summer.
And Faurlin quickly adapted to the English game, being named the club's player of the year last season by both players and supporters.
The 24-year-old has continued to shine during the R's unbeaten start to the new campaign, which sees them top the Championship table by six points after 10 games, and he has been rewarded with a new deal that ties him to the Hoops until 2014.
Warnock took charge last March and despite signing the likes of Jamie Mackie, Adel Taarabt and Paddy Kenny over the summer, he believes Faurlin's new deal is his biggest coup at Loftus Road.
"It's the best signing I've made," he told the club's official website. "I couldn't be more delighted that he's penned a two-year contract.
"I genuinely believe he can get better and better, and that's saying something because he's already a truly outstanding player.
"I've got great confidence in his ability and he's an intergral part of where I see the club going in the future.
"I think it says a lot about his character and his temperament that he's settled in so quickly.
"It took him the best part of six months to bed in, but this contract and the stability it provides will take his game to the next level now."
Rangers received another boost on Tuesday with youth product Bruno Andrade signing a professional contract with the club.
The 17-year-old has been with the Hoops since the age of 13 and has put pen to paper on a two-and-a-half year deal after impressing with the Under 18s this season.
"He's an exciting young player," Warnock added. "All the staff have been pleased with him. It's a challenge for him now to try to get into the first-team squad.
"All the younger lads here know that I will give them every opportunity. I think Bruno is going to be a big favourite for many years to come.
"There will be a lot of people looking at Bruno over the next few years so we are delighted he has committed himself to QPR.
"He is just the type of lad we need. He will excite people because he's a got a bit of pace, can finish, is able to play in different positions, and I am looking forward to getting him in the first team."
