Former Chelsea and Liverpool midfielder Boudewijn Zenden has joined Sunderland until the end of the season after impressing while training on Wearside.
The 33-year-old Dutchman has been signed as a free agent after leaving Marseille during the summer. He had been on trial at the Wearsiders and the experienced international did enough to impress boss Steve Bruce.
International clearance has been granted and Zenden, who has 54 senior international caps, will go into the squad for Saturday's Premier League clash with Liverpool.
Zenden will provide cover in midfield for Sunderland, who also have the option of extending his deal until the summer of 2011.
The Wearsiders are short of numbers in the middle of the park after Dean Whitehead, Grant Leadbitter and Carlos Edwards were sold in the summer while Teemu Tainio was allowed to join Birmingham on loan.
Zenden rose to prominence at PSV Eindhoven before moving on to Barcelona, Chelsea, Middlesbrough and Liverpool.
He joined Marseille in 2007 and spent two seasons at the Stade Velodrome before opting to leave at the end of last season.
Sunderland boss Bruce revealed he was delighted to add an experienced international to his squad.
"We are delighted to be able to add a player of Bolo's quality to the squad," Bruce told the club's official website. "He has performed at the highest level year after year and he's done extremely well during his time training with the club.
"The move happened fairly quickly. Bolo came in and it was immediately obvious that he was still supremely fit. Bolo's performances in training have persuaded me that he has a valuable role to play this season.
"He brings international class, a steadying influence and a wide breadth of experience. His career is a testament to his quality and he gives us more depth in midfield which is a vital position.''
