Jamie Carragher has claimed Cristiano Ronaldo's return to Manchester United will cause 'as many problems as it solves' for Ole Gunnar Solskjaer this season.
Ronaldo made a stunning move to Old Trafford at the end of the summer transfer window, 12 years on from leaving the club to forge a record breaking career.
The 36-year-old has wasted no time getting off the mark for United, scoring two goals in a victory over Newcastle before adding one in a shocking 2-1 Champions League defeat to Young Boys.
Carragher in his column for the Telegraph has questioned whether Ronaldo's arrival gets them any closer to challenging for their first title since 2013.
