Leicester forward Leonardo Ulloa has vowed never to play for the club again and feels "betrayed" by Foxes manager Claudio Ranieri.
The 30-year-old joined from Brighton in 2014 but handed in a transfer request this month and said on social media he had been "let down by the club".
Leicester have reportedly rejected a bid from Sunderland with Ranieri saying he does not want to sell the striker.
Ulloa has started only one league match this season and has scored one goal.
