Cristiano Ronaldo has been left angered by interim Manchester United boss Ralf Rangnick 's comments, according to reports.
Ronaldo made a return to Old Trafford last summer in a move which left Red Devils excited for this season, but things have not turned out as hoped with United struggling for form.
The side's difficulties on the pitch led to Ole Gunnar Solskjaer's sacking and ultimately Rangnick's arrival, but the Portuguese forward is reportedly unhappy with life under his new boss.
