Fulham have opened talks over a new deal for Tosin Adarabioyo to ward off any interest this summer.
The defender played almost every game as Marco Silva's side won the Championship title at a canter but has just one year remaining on his current contract.
Silva is now keen for the club to quickly tie the towering centre-back down to a fresh long-term deal.
Given his Premier League experience, having played 33 games during Fulham's last top-flight campaign, rivals may see the former Manchester City man as a bargain option this summer.
Fulham, however, are determined to keep Adarabioyo, 24, at the heart of their back line as they look to break the yo-yo cycle of promotion and relegation in recent years.
The Craven Cottage hierarchy are looking to strengthen in defence alongside Adarabioyo - who attracted Premier League interest last summer and in January but opted to stay put and get the west Londoners back into the big time.
Newcastle and Arsenal were both linked last time out and Fulham are keen to fend them off once more.
Cottagers vice-chairman Tony Khan is responsible for the transfers and is already working to build on the squad which took the Championship by storm.
In order to avoid another relegation, Khan is keen to keep as much talent as possible.
