Coral have suspended all bets on Tottenham Hotspur manager Mauricio Pochettino to leave the club after a high volume of bets on the market.
There were odds of 1/6 given for the Argentine to leave, despite his side picking up seven out of a possible nine Premier League points so far this term.
Speaking to the Daily Mirror, Coral spokesman John Hill said the decision to prevent any more bets being placed "has taken us by surprise".
"This is a gamble which has taken us by surprise and as a result of the volume of bets we have taken, we have had no choice but to suspend betting to let the dust settle as there is rarely smoke without fire when it comes to such activity in our managerial markets," Hill said.
The future of Spurs star Christian Eriksen is still uncertain, with the Danish international linked with a move away as his contract enters its final year.
Another report earlier on Thursday suggested that midfielder Victor Wanyama had agreed an exit from North London.
