La Liga - Rubin deny Kaka bid, want Martins back
Russian side Rubin Kazan denied reports that they offered Real Madrid 45 million euros for Kaka, and insisted Obafemi Martins will return to the club after his loan spell at Birmingham.
"Of course, we've heard these rumours, it's absolutely ridiculous," a club spokesman told Russian media.
Spanish sports daily Marca reported that Rubin had bid for the 28-year-old Kaka, who has been struggling with injuries this season.
Rubin added, however, that they want Nigerian striker Martins back after his loan deal with Carling Cup winners Birmingham City expires at the end of the season.
Martins signed a six-month loan deal with Birmingham just before the transfer window closed on January 31 with an option for a permanent move to the Midlands club, but Rubin coach Kurban Berdyev said he wanted the 26-year-old to return.
"Martins left Rubin due to personal reasons," Berdyev was quoted as saying by the Daily Mail.
"We agreed that he will stay there until the summer and then return to Kazan."
Martins has failed to establish himself as one of the key players for Rubin after joining them from Bundesliga side VfL Wolfsburg last July.
But he showed that he had not lost much of his scoring touch by sweeping home a last-minute winner for Birmingham in a 2-1 upset victory over Arsenal just six minutes after coming on as a substitute in the League Cup final at Wembley Stadium on Sunday.
Despite his cup heroics Berdyev said Rubin have had no offers for Martins: "We haven't received any formal offers from Birmingham."
