The Portuguese attacker is in incredible form for the European champions but his former team-mate believes the German side can stop him
James Rodriguez admits his Bayern Munich side must overcome a "goal machine" in Cristiano Ronaldo if they are to edge past Real Madrid in the Champions League.
Ronaldo is the runaway top scorer in this season's competition with 15 goals in 10 games and will be hoping to improve on his devastating recent form when his side travel to Munich for the first leg of their semi-final tie.
The Portuguese star helped fire Madrid past Bayern in the quarter-final stage last term, scoring five in a 6-3 aggregate win en route to helping lead Zinedine Zidane's men to another European crown.
