Chelsea have completed the signing of Ross Turnbull from Middlesbrough on a free transfer.
Boro announced at the end of the 2008/9 season that the goalkeeper would be leaving The Riverside when his contract expired on 30th June.
A number of clubs were reportedly interested but Chelsea always appeared favourites and have now secured his services on a four-year deal.
The 24-year-old enhanced his reputation with a series of number of eye-catching performances for Boro in the Premier League last term.
He had previously spent time out on loan with Barnsley, Crewe and Cardiff earlier in his career.
Turnbull will now be looking to make an impact at Stamford Bridge after joining Petr Cech and Hilario as the goalkeepers in Carlo Ancelotti's first-team squad.
Chelsea's shot-stopping options had been limited during the second half of last season following Carlo Cudicini's switch to Tottenham.
Hilario provided the back-up to Cech and Turnbull is now expected to vie with the Portuguese player for the right to be second choice.
Hilario, 33, has also put pen-to-paper on a new two-year contract that ties him to the club until 2011.
