Kieran Trippier claims Diego Simeone warned him about Alexander Isak’s potential while at Atletico Madrid. The Swede arrived from Real Sociedad last month for a record-breaking fee and made an instant impact on debut.
A goal against Liverpool gave Toon supporters a glimpse of what is to come and a second was controversially ruled out by VAR for offside. In Callum Wilson and Allan Saint-Maximin’s absence, Isak bore the brunt of Newcastle United's attacking responsibility in his first two games on Tyneside.
Trippier knows all too well about the 22-year-old’s capabilities from his spell in La Liga. The duo clashed last October and Isak put in a man-of-the-match performance against the reigning champions.
