Emre Can says he would never play for Manchester United.
The Borussia Dortmund spent four years at Liverpool before joining Juventus in 2018.
Asked by Bild about the similarities between United and his first clubBayern Munich, Can said: "The comparison fits.
"Both are record champions and have huge strength. In addition, big names like Bastian Schweinsteiger and Owen Hargreaves played for both clubs.
"But I would never play for United because of my time in Liverpool. My heart won't let me do that. The rivalry between the clubs is really huge."
