Chelsea midfielder Joe Cole believes the Barclays Premiership champions have shown their intention to improve next season by signing Germany international Michael Ballack.
Ballack, the 29-year-old midfielder who is out of contract with Bayern Munich, is set to be unveiled at Stamford Bridge today after several weeks of discussions over a salary reported to be worth £130,000 a week.
Cole said: 'It's fantastic for the club. He's a world-class player, the more world-class players we have, the more games we'll win and the more titles we'll win.'
