Ajax will head to Russia for their second leg of their Champions League play-off all square after being held 1-1 by Rostov in Amsterdam.
Rostov stunned the home side when taking an early lead through midfielder Christian Noboa’s 13th-minute free-kick, but Ajax responded before the break through Davy Klaassen’s 38th-minute penalty for Cesar Navas’ foul on Riechedly Bazoer.
Ajax created a host of chances and were denied on several occasions by Rostov goalkeeper Soslan Dzhanaev.
Dinamo Zagreb were also held 1-1 at home by Austrian side Red Bull Salzburg.
Valentino Lazaro headed Salzburg into a 59th-minute lead and the Croatian side were rescued by Marko Rog's 76th-minute penalty after he had been fouled by Bernardo.
FC Copenhagen will defend a slender 1-0 lead in the return leg in Cyprus after beating Apoel Nicosia 1-0 thanks to Andrija Pavlovic's angled drive two minutes before the break.
Borussia Monchengladbach are in the box seat in their tie against Young Boys following a 3-1 win in Bern.
Young Boys, who knocked out Shakhtar Donetsk in the third qualifying round, went behind in the 11th minute when Raffael fired home from outside the box — but they equalised through Miralem Sulejmani's close-range finish in the 56th minute.
The German side regained the lead through Andre Hahn's emphatic finish in the 67th minute and opened up a two-goal cushion two minutes later when Young Boys defender Alain Rochat deflected Raffael's shot into his own net.
