The Blues wasted no time diving into the transfer market by securing the Porto right-back's signature for a £16.1million fee only a day after missing out on the Premier League title to Manchester United.

United were also chasing Bosingwa but the 25-year-old has opted to join Chelsea on a three-year deal and will link up with his new team-mates after playing for Portugal in this summer's European Championships.

He told Chelsea TV: "I have friends who are at Chelsea and it's a club I feel I can improve at and grow as a player.

"I've always had a dream to play in England - I always watched the Premier League as a child, I love the English game and now I'm here, I'm going to work to do my best.

"I played for a big team in Porto and now I'm going to play for a bigger team in Chelsea. My aim is to win titles."

The Portugal international's arrival will place more speculation around the future of Juliano Belletti. The Brazilian has been sidelined in recent weeks, with Michael Essien playing at right-back.

Chelsea's other right-back, Portugal'sPaulo Ferreira, signed a five-year deal earlier this season and is unlikely to move on.

Kinshasa-born Bosingwa moved from Boavista to Porto in 2003 - where he played under former Chelsea boss Jose Mourinho - and has been their first-choice right-back for the last three seasons.

Meanwhile, Mikel John Obi insists the Blues can conjure up another slice of cup glory after failing to pip United for the Premier League title.

The Blues' 1-1 draw with Bolton and United's victory over Wigan on Sunday meant Sir Alex Ferguson's men retained their crown.

It was Ferguson's 10th Premier League title but Mikel insists Chelsea's eyes are now firmly focused on beating United in the final of the Champions League in Moscow a week tomorrow.

Last season, the Blues lost their league title to United but went on to beat them 1-0 in the first FA Cup final at the new Wembley.

And Mikel insists his side have set their sights on repeating the feat in Moscow with the Champions League trophy as the prize this time.

"There is a sense of frustration but determination among everyone," said Mikel.

"At the end of the day, we wouldn't have won the title anyway. We wanted to win and we knew that three points was our only chance of beating Manchester United, but it wasn't to be.

"We were saying to each other afterwards that we would put things right in Moscow. We will keep working hard until the final and make sure we win the Champions League.

"Last year, they won the league and we beat them in the FA Cup final. They have won the league again but we know that we're good enough to beat them.

"They're a very good side, we all know that, but we have to focus on the day. I think we're going to win it."
