A hamstring injury will keep Cristiano Ronaldo out of Real Madrid's Champions League match with Galatasaray, Blancos coach Carlo Ancelotti said Tuesday.

"Cristiano can't play tomorrow. He has had a very small problem. Tomorrow he begins to work out individually on the field and we'll see if he can be available Saturday," Ancelotti told a press conference.

The club's next La Liga match is set for Saturday.

"It's clear that if we have the risk he can be injured, we won't put him in on Saturday," the coach said.

The Portuguese international delivered the first goal in the Blancos' 5-0 rout of Almeria last Saturday to move into a tie with Di Stefano for second place on the club's all-time scoring list.

Ronaldo asked to be taken out in the 52nd minute of the contest after noticing some extra discomfort after a rough tackle.

Real Madrid's Medical Services examined the 28-year-old forward at the Sanitas La Moraleja hospital and determined he had suffered an injury to the hamstring in his left leg.

Either Angel Di Maria or Jese will replace Ronaldo for Wednesday's clash in Madrid against Galatasaray, Ancelotti said.

Real Madrid needs only a tie to be sure of advancing to the Round of 16, but the coach said his side wants to win its last two matches of the group phase to ensure a first-place finish in Group B.

The Blancos embarrassed Galatasaray 6-1 in Istanbul in their first 2013-2014 Champions League contest back in September. EFE
