Coming into the match with a comfortable 3-1 advantage from the first leg, Bremen were back on level terms at the interval after a strike from Gokhan Inler and a Fabio Quagliarella brace either side of Diego's effort had made it 4-4 on aggregate.

But the Germans were a different side after the break and in the end, could even afford to miss a penalty as Diego's second and a further goal from Claudio Pizarro were enough to send Thomas Schaaf's side through

Dynamo Kiev benefited from two goalkeeping gaffes by Mickael Landreau to ease past Paris St Germain.

The tie was well poised after last week's goalless first leg at the Parc des Princes but PSG were no match for Dynamo seven days on - although the French side was not helped by a couple of costly clangers by Landreau.

Ismael Bangoura put the hosts ahead in the fourth minute and Landreau punched the ball into his own net soon after to leave PSG with a mountain to climb.

Worse was to come for the 11-times-capped France custodian, who spilled a free-kick to allow Ognjen Vukojevic to slot home Dynamo's third just after the hour mark.

Manchester City rediscovered that winning mentality but it was Hamburg which secured a place in the semi-finals.

Hamburg extended their aggregate lead to 4-1 after only 11 minutes at Eastlands. City failed to deal with a routine cross from Jonathan Pitroipa and Paolo Guerrero took full advantage to score from close range.

However, City battled back and goals from Elano - with a penalty - and Felipe Caicedo gave them hope.

But City were left cursing their luck as Elano twice had superb free-kicks come back off the woodwork and their  misery was compounded when skipper Richard Dunne was sent off in the second half.

Shakhtar Donetsk set up an all-Ukrainian UEFA Cup semi-final against Dynamo Kiev by securing a smash-and-grab triumph over Marseille at the Stade Velodrome to complete a comfortable aggregate victory.

Shakhtar built on their 2-0 home win in last week's quarter-final first leg by going ahead on the half-hour mark through Fernandinho.

Needing to score four goals without reply, OM pulled one back when Hatem Ben Arfa slammed home two minutes before half-time but that was all they could muster.

After soaking up lots of pressure, Shakhtar broke forward three minutes into second-half stoppage time and Luiz Adriano finished with aplomb to seal victory on the night.
