Dusan Vlahovic made a dream start to his Champions League debut with a goal, but it wasn’t enough to secure victory for Juventus.
The Serbian striker fires his side ahead at Villarreal with a cool finish after just 31 seconds.
But Villarreal equalised in the second half after Dani Parejo latched on to a brilliant ball from former Watford star Capoue.
Nothing separates the two sides as they head into the second leg of this Champions League round-of-16 fixture.
Juventus will host Villareal in Turin on March 16 to determine who advances to the quarter-finals.
