Although Ajax were given a free-kick for the initial foul on Neres, the referee showed a yellow to Tagliafico for his foul on Cancelo and this rules him out of the second leg.
Cristiano Ronaldo returned from injury and headed Juve into the lead just before half-time but Ajax fully deserved the equaliser scored by David Neres straight from the restart and pushed hard for a victor. To beat Juventus as well would be the stuff of legend. Most viewers will be hoping that history repeats itself.
After being out for the past two weeks for Juventus due to a thigh strain injury sustained on global duty, Cristiano Ronaldo looks set to return against Ajax.
Juventus only displayed their attacking threat in patches, with Federico Bernardeschi lively and Ronaldo hooking one chance wide.
"You messi fanboys really think Ronaldo will allow ajax to go through?" said another supporter.
Ajax dominated the ball against a team of such stature and had 62.6% possession by when the game ended.
After sensationally dumping out defending champions Real Madrid in the round of sixteen, Ajax will be targeting the scalp of Juventus on Wednesday evening.
It is unlikely that Massimiliano Allegri's side will be so generous at the Allianz Stadium, so it is hard to shake the feeling that Ten Hag's men might live to regret not taking a lead to Italy.
Ajax then had to ride their luck as Juve substitute Douglas Costa, returning from two months out with a thigh injury, raced into the area and crashed a shot against the far post.
Van der Sar later played for Juventus. It would have been a soft penalty to give but Manchester City's penalty against Spurs was even softer.
Ajax have come from behind to score the equaliser more often than any other team this Champions League season (six times). Ajax will try to win this home leg but with the quality of Juventus, I see the Italian side winning away from home since they will have many scoring chances.
"In the return we'll have to give everything because Juventus are incredibly hard".
