Chelsea: Didier Drogba wants to stay at Stamford Bridge
"Since last year, there have been two firm offers: Inter and Manchester City, who offered me a golden deal," Seydi told Senegal newspaper L'Observateur.
"I was quite ready for it, Didier also, but the Chelsea board said 'no'. They turned down 20 million euros for a 30-year-old.
"That's proof of the confidence they have in Didier. And the president was right to keep Didier, because since he has come back, Chelsea are winning."
Meanwhile, Chelsea's England defender Ashley Cole could face the wrath of Hiddink after the left-back was arrested on suspicion of being drunk and disorderly in the early hours of this morning.
The 28-year-old left-back was arrested in Brompton Road, South Kensington, at about 2.15am after emerging from the Collection nightclub.
He was taken to a central London police station and issued a fixed penalty notice before being released shortly after 5.30am.
A Scotland Yard spokesman said: "We can confirm a 28-year-old man was arrested at approximately 2.15am in Brompton Road on suspicion of being drunk and disorderly.
"He was taken to a central London police station where he was issued with a fixed penalty notice for being drunk and disorderly and released shortly after 5.30am."
Cole is likely to be fined by the club and is the second Chelsea player to be arrested inside two months. Midfielder John Obi Mikel was charged with driving while over the drink-drive limit in January and is set to appear in court next month.
Before his arrest, Cole was pictured at a nearby charity event with former GMTV presenter Fiona Phillips.
Cole joined Chelsea's first-team squad and more than 300 charity workers, celebrities and supporters for the second annual Chelsea Football Club and Armani charity fundraiser.
"Children from Chelsea's two official charity partners, Clic Sargent and Right To Play, joined the players at the Armani Store on Brompton Road where they pitted their talents against the team on Scalextric, computer games, table football and pool," according to a statement on the club's website.
"Funds were raised for the two charities via an auction that was auctioneered by Chelsea and England captain John Terry.
"Other guests included former Formula One supremo Eddie Jordan, Graeme Le Saux, TV presenter Alice Beer and Lady Helen Taylor."
A spokesperson for Chelsea said: "We are aware that Ashley was detained last night. We will want to establish all the facts before commenting."
