After having bids turned down for Fulham's Tom Cairney and showing interest in Everton's Morgan Schneiderlin as well as Ibrahim Amadou of Lille, West Ham have had another bid rejected on Deadline Day.
Dendoncker, who is an important player for Anderlecht and has featured in 30 matches for the Belgian side this season, will stay put at Anderlecht despite being tracked by several Premier League outfits in January.
The 22-year-old is comfortable playing in the centre of midfield or the centre of defence, and has made four caps for Belgium.
