Former Rangers loan star Malik Tillman will be worth up to £120 million soon if he keeps progressing according to Dutch TV pundit, former Ajax star Kenneth Perez.

Tillman made his loan move from Bayern Munich to PSV Eindhoven permanent last week in a £12 million deal, landing Rangers a reported £1.2 million windfall after the German giants had a change of heart about an agreed deal to allow the Ibrox club to sign him after his loan spell at Ibrox.

Rangers received around £1 million in compensation after the Bundesliga club pulled out of the agreement and a further 10 per cent sell-on fee was included in the settlement.

And former Danish international Perez reckons Tillman, who signed a four-year deal at PSV, will go on to become of the most expensive players in the world.

He said: "Arne Slot always says at Feyenoord that his players must first learn to work hard and apply pressure. If Tillman also learns that at PSV, then they have really made a good move.

"That £12 million will soon become £120 million.

"I really thought he was great, especially in the second part of the season, in everything actually. Even in defending, which he has become very good at.

"He's the best player at the club and there is much more to come from him."
