As the ink dries on Frank Lampard's new Chelsea contract, reported to be worth an amazing £39.1m over five years, the club are set to keep Didier Drogba and Joe Cole waiting on their expected new deals. Lampard agreed a five-year deal said to be worth £151,000 a week after around two years of negotiation with his previous contract within 12 months of expiring. Both Drogba, long expected to leave London but who has recently stated his desire to remain at Chelsea, and Cole, a lifelong fan who would expect to see out most of his career at the Bridge, have two years left on their current contracts. Chief executive Peter Kenyon, in restating his club's policy in contract negotiations, intimated that both will have to wait until 2009 to secure their new deals. 'Both those contracts and discussions have been put on the shelf. The season is starting and those will be re-visited next year.' Kenyon has not given up on transfer business however. He said that Chelsea are still hopeful of signing Robinho from Real Madrid. He said: 'It is continuing. Hopefully not as long as the speculation about Frank. We've still got a few days left of the window and hopefully we'll get a result.' Meanwhile, Branislav Ivanovic's agent claims Chelsea have told AC Milan that the Serbian defender is not for sale. The 24-year-old arrived at Stamford Bridge in January from Lokomotiv Moscow at a cost of £10 million, however he is yet to play a single first-team minute for the Blues. A loan deal could yet see Ivanovic move to Serie A, but Chelsea are not prepared to sanction a permanent move, with agent Vlado Borozan telling Tuttomercato.com: 'Chelsea have made it known to us that he is indispensable.'
