Cristiano Ronaldo did it again as he scored a vital away goal for Juventus in their 1-1 draw at Champions League quarterfinal opponents Juventus.

Ronaldo, who has won the competition five times, netted his 125th Champions League goal just before half-time with a diving header following Joao Cancelo's cross.

The goal had come against the run of play, but the hosts equalised within a minute of the second half starting, through David Neres' fine curling effort from 15 yards.

Ronaldo was playing for Juventus for the first time since he scored a hat-trick to give them 3-2 aggregate victory against Atletico Madrid in the last 16.

He picked up a thigh injury on international duty for Portugal and there were doubts whether he would be fit enough for the tie.

Both teams had late chances with Ajax's Jurgen Ekkelenkamp having a shot saved before Juventus substitute Douglas Costa hit the post.

But neither side could grab a winner and they meet in the second leg in Turin on Tuesday, 16 April.
