Erik ten Hag has said his Ajax side must ''concentrate'' if they want to overcome Juventus on Tuesday.
'Juve' are favourites to reach the last four after drawing the first leg of their quarter-final 1-1 in Amsterdam last week, when Cristiano Ronaldo's 125th UCL goal was cancelled out by Ajax's David Neres.
But Ajax, ahead of closest challengers PSV Eindhoven on goal difference at the top of Eredivisie, pulled off a stunning second-leg result against Real Madrid in the previous round.
Ten Hag's side lost the first leg at home 2-1, but stormed to a 4-1 win in the return leg at the Bernabeu to win a Champions League knockout tie for the first time in 22 years.
Midfielder Frenkie De Jong, who will join Barcelona in the summer, is struggling with a hamstring strain but has not been ruled out.
