Middlesbrough have resisted a third bid from West Bromwich Albion for centre-half Ben Gibson.
Albion are up to £18million plus £3m in add-ons with their latest offer and Gibson is keen to stay in the Premier League.
The 24-year-old was ever-present for Middlesbrough last season, starting all 38 of their Premier League games, a streak he wants to continue with a new club in the upcoming season.
Boro, relegated after one season in the top flight, are determined to only sell Gibson to one of the top six and are aware of long-standing interest from Tottenham.
