Defending a 2-1 lead from the first leg, OM went behind in the Dutch capital when Eyong Enoh scored just after the half-hour mark but Mamadou Niang put the visitors back in front in the tie two minutes later.

Miralem Sulejmani, with a close-range second-half header, took the last-16 game into extra time but former Derby right-back Mears was the matchwinner in the 108th minute.

Earlier Werder Bremen became the first club to book their place in the quarter-finals after a 2-2 draw at St Etienne completed a 3-2 aggregate win.

The Bundesliga side's passage to the last eight never appeared in any doubt, after Sebastian Prodl headed them in front in the sixth minute.

Claudio Pizarro added a second in the 28th minute.

But Yohan Benalouane scored what appeared to be a 64th-minute consolation for the home side, and Sebastian Grax then grabbed a last-minute equaliser to earn St Etienne some respect despite their elimination.
