Chelsea became the fifth club of the 25-year-old's professional career yesterday when he signed on loan from the Serie A giants until the end of the season.

After an unsuccessful spell at Barcelona, the Sporting Lisbon trainee moved to Porto before he was snapped up by Inter boss Jose Mourinho last summer for 18million euros (£16.3million).

Despite scoring on his debut, the Portuguese winger failed to establish himself at the San Siro and was criticised by Mourinho for what he saw as the winger's poor work-rate.

After making just 12 starts for Inter, Quaresma admitted he was glad to leave the Italians for Stamford Bridge, where the man whom he used to play under with Portugal - Luiz Felipe Scolari - is currently manager.

"I didn't have many opportunities to show my qualities at Inter," Quaresma told Chelsea TV.

"I am really glad I have this opportunity to play with such a good club as Chelsea."

Chelsea's defeat at Liverpool on Sunday leaves them five points adrift of Barclays Premier League leaders Manchester United, who have a game in hand.

Quaresma is, however, hopeful that he can put Chelsea's faltering quest for silverware back on track.

"Now I aim to play the best that I can to help Chelsea to achieve their goals because all I want is to show my qualities, to show what I am made of and hopefully I am going to help Chelsea achieve their goals," he added.

"Obviously Chelsea is a great club and it has great quality players and I am very proud that I can have the chance to represent such a great club."

Quaresma was the only player to arrive at Stamford Bridge in the winter transfer window while Carlo Cudicini and Sergio Tejera left for Tottenham and Real Mallorca respectively.

He can play on either flank and will compensate for the absence of Joe Cole, who has been ruled out for the rest of the season with a knee ligament injury.

Quaresma, who has 24 international caps, will now compete with Florent Malouda and Salomon Kalou for places.

"I believe the competition is good and these two are players that I admire," he said.

"My intention is to work hard to gain my place in the team and I believe competing with great players is what makes you a better player.

"I am going to give my best, I am going to prove that I deserve to be in this team and that I am the right player to help Chelsea achieve their goals. Hopefully I will be able to do so."

Quaresma joins countrymen Deco, Jose Bosingwa, Paulo Ferreira, Ricardo Carvalho and Henrique Hilario at Stamford Bridge and he believes that will help him settle into life at the club.

"With all the other Portuguese players, I am sure it is going to be easier for me and I am very glad to be here with them," he added.

"I hope to please the supporters as much as I hope to please the team because that is what we play for, that is what motivates us."
