Blackburn chairman John Williams has warned rival clubs they will strongly resist all attempts to lure manager Sam Allardyce away from Ewood Park.
Reports on Monday suggested Allardyce was on a four-man shortlist for the vacant West Ham job after Gianfranco Zola was sacked earlier this month.
However, no official approach has been made to Blackburn and Williams told the Lancashire Telegraph: "There's been no approach and we wouldn't welcome any approach."
In the 18 months since taking over from Paul Ince, Allardyce has lifted Rovers from relegation candidates into the top half of the table with a 10th-placed finish this season.
The Rovers boss has achieved that success on a very limited budget but is now looking to get the club back into Europe, having last played in the UEFA Cup in 2007-08.
