If history is anything to go by, Ronaldo is incredibly likely to have a big say in deciding this tie.
During his time with Real Madrid, who were knocked out by Ajax in the last round, the Portuguese talisman filled his boots against the Eredivisie side.
Cristiano Ronaldo has fired a staggering seven goals against tonight’s opponents in his past four meetings with Real Madrid. He has scored the most goals against them in the compeititon out of all the quarter-finalists, making it the best possible draw.
That includes a hat-trick on his last visit to the Johan Cruyff Arena in a group match for Los Blancos in October 2012 as his side won 4-1.
It was one of the best individual performances the stadium has ever seen, with his second and third goals a mark of his show-stopping ability.
What bodes even better for Juventus, is that the hat-trick inspired Ronaldo to continue that form in the league the following weekend, where he again struck three times against Deportivo La Coruna.
Memories of those previous ties have haunted the Amsterdam club ever since the draw was made last month in Nyon, Switzerland.
Ronaldo has also won all of his five matches against Ajax, meaning Erik ten Hag will be increasingly fearful for his side heading into the two legs.
Ajax showed in the previous round that they will be no pushovers and Real Madrid will restore some satisfaction if their former hero Ronaldo can take them apart tonight as an act of revenge.
Ronaldo currently has 124 Champions League goals and he will be looking to extend his record as the competition’s all-time top goalscorer tonight.
The winger will start tonight’s Champions League quarter-final first leg against Ajax.
Ronaldo has been nursing a thigh strain, picked up upon his international return with Portugal last month.
The star’s last game for Juventus came against Atletico Madrid in the Round of 16, where he scored a hat-trick to turn the tie on its head at the Allianz Stadium.
With the Old Lady just one point away from the Serie A title, their attentions have turned to Europe’s elite club competition which they haven’t won since 1996.
Manager Massimiliano Allegri claims that barring any late change in circumstances, Ronaldo will definitely start the match at the Johan Cruyff Arena.
“Cristiano has trained with the team and is available,” said the Italian.
Daniele Rugani believes Ronaldo is looking in good shape ahead of the clash.
He said: “Cristiano looks the same as ever. He’s in good shape, a very important player for us, as everyone knows, and we are happy he’ll be with us tomorrow.”
