The four-time European champions took the lead in the 57th minute, a minute after Dynamo were reduced to 10 men.

Denys Garmash was ordered off for a second bookable offence, a foul on Jan Vertonghen.

And Ajax made them pay when Demy de Zeeuw's free-kick picked out Vertonghen who headed home, only to let in an equaliser nine minutes later when Oleh Gusev fired home.

Russian league leaders Zenit St Petersburg will carry a 1-0 lead into the second leg of their play-off against French side Auxerre, thanks to Aleksandr Kerzhakov's header in the third minute.

Steffen Iversen and Markus Henriksen scored for Rosenborg as they beat FC Copenhagen 2-1. The Danes pinched a late consolation through Jesper Gronkjaer to give themselves hope ahead of the second leg, when they will have home advantage.

Slovakian side Zilina put themselves into a strong position to qualify for the group stages for the first time in their history as they seized a 2-0 lead against Sparta Prague.

Momodou Ceesay fired Zilina in front after 51 minutes and the lead was doubled when Tomas Oravec headed home in the 73rd minute.

Swiss side Young Boys caused a major shock by beating Tottenham 3-2 in Bern.

Tottenham will nevertheless be delighted with a comeback from 3-0 down after a humiliating half-hour at the Stade de Suisse in which their hapless defence was torn to shreds.

Goals from Senad Lulic, Henri Bienvenu and Xavier Hochstrasser did the damage but Sebastien Bassong scored just before half-time and Roman Pavyluchenko struck late on to ensure Harry Redknapp's men will remain favourites ahead of next Wednesday's second leg.
