Chelsea have told Mason Mount he's a required player.
The Sun says Mount, 19, has made a huge impact in his debut year in senior football while on loan at Vitesse Arnhem.
The midfielder scored a stunning hat-trick and created another in the club's 5-1 Eredivisie play-off win over Den Haag this week to add to his growing reputation.
Chelsea bosses are now debating whether to scrub plans for a second year out on loan to accelerate him into the first team squad at Stamford Bridge.
Mount has made such an impression in Holland that champions PSV and Ajax have both asked about signing him this summer.
