Juventus president Andrea Agnelli has hinted it may not risk Cristiano Ronaldo for the first match of the Champions League quarterfinals against Ajax.

Ronaldo injured a muscle in his right thigh and limped off 30 minutes into Portugal’s 1-1 draw against Serbia on Monday in qualifying for the 2020 European Championship.

Agnelli says on Friday “when you have muscle injuries you have to be very careful,” and adds “for one match you risk compromising the next two months.”

Juventus has said the injury is “apparently minor,” while Ronaldo told Portuguese media after the match he “should be back in one or two weeks.”

Juventus travels to Ajax for the first leg of the Champions League quarterfinals on April 10, then hosts the Dutch team the following week.

Agnelli adds: “It’s more important to safeguard two and a half months than one match only.”

Ronaldo scored a hat trick against Atletico Madrid in the return leg of the last 16 as Juventus overturned a first-leg deficit.
