Manchester United have made contact to sign Sporting CP striker Viktor Gyökeres but will face competition from Manchester City, Paris Saint-Germain, Bayern Munich and Barcelona, reports Corriere dello Sport, which adds that the 26-year-old will be available for €70 million rather than his €100m clause. The Red Devils hope he will replace Joshua Zirkzee, who is receiving interest from Juventus, Napoli and Internazionale.
