Cristiano Ronaldo's Quest for Champions League Scoring Record Could be Thwarted by Injury

Real Madrid superstar Cristiano Ronaldo is close to making history in the Champions League, but his attempt to set a new secoring record may be thwarted by injury.

Last week CR7 scored his 14th Champions League goal of the season, equalling the tallies of Barcelona's Leo Messi [in 2011/12] and the legendary Milan striker Jose Altafini [in 1962/63].

However the Portuguese international's quest for a 15th strike may have to be put on ice, as an injury threatens his participation in tonight's match against Borussia Dortmund.

During training ahead of the match, the superstar felt pain in the patellar tendon and left the pitch looking worried – he had only completed 20 minutes of the session.

Ronaldo missed the weekend's league win against Real Sociedad after the injury first flared up, and Real boss Carlo Ancelotti hinted that he may leave out his star player in Dortmund.

"We will make a decision without risks" Ancelotti said. "If he is at top form, he will play. Otherwise, no."

Real are 3-0 up from the first leg and are likely to progress, so Ancelotti may decide to rest Ronaldo - but he will probably get another chance to break the record in the semi-finals.

Ancelotti looks likely have a fully fit Gareth Bale, going for his 19th goal of the season, at his disposal. The Italian coach said: "'Gareth Bale picked up a knock on Saturday but he has recovered and is available."
