Southampton have joined Norwich in the race to sign Fulham centre-back Tosin Adarabioyo.
The former Manchester City defender, who joined the Cottagers for around £2m last summer.
City are set to net 20 per cent of any future fee though after including a sell-on clause in the deal.
At 23, Adarabioyo fits Southampton's transfer policy to a tee and he was impressive in the top-flight last season under Scott Parker before Fulham's relegation.
Southampton are looking to sign a new centre-back to replace the experienced Jannik Vestergaard following his £15m switch to Leicester last week.
Norwich have also shown interest earlier in the window and they are now prioritising the signing of a new central defender after recently landing attacking duo Josh Sargent and Christos Tzolis.
