The Black Cats have splashed out an initial £7million for Gordon, who has signed a five-year deal, with the prospect the fee could rise to £9million due to a number of clauses attached to the deal. That would beat the previous British record for a keeper, eclipsing the £7.8million Manchester United paid Monaco for Fabien Barthez in 2000.
Keane knows he has a top drawer player, saying: "I rate him very highly. I think he can only get better, and this is the right club for him because we´ve good goalkeeping staff here."
