The Congolese centre-back, who joined the Hoops in the January transfer window with the aim to help the club avoid relegation, signed a contract reported to be around £100,000-a-week.
For Anzhi chief, the effort made by the English club sounds excessive and no one there could believe QPR were willing to pay the release clause, he told the Russian news site www.sports.ru.
“At QPR he will earn almost as much as he did at Anzhi. In my view QPR have lost their minds”, he declared.
“When they agreed to pay his release fee we wept. He [Samba] wept. Everybody says that he ran away from the club, but that’s not true. He didn’t put any pressure on the club until we received an offer from QPR for £12.5m, the amount required by his contract”, Tkachenko added.
Tkachenko revealed that former Blackburn Rovers defender was keen to return to Russian football due to family reasons.
“It was linked to the threat that he would lose contact with his children”.
For QPR manager Harry Redknapp there is no doubt the £12.5 million effort will be money well spent, as he described Samba as a “monster”, and denies the player could burden financially the club if they end up being relegated: “There will be takers for Samba all day.”
