Barcelona bundled out of Europa League quarter-final after chaotic loss to Eintracht Frankfurt

Underdogs Eintracht Frankfurt have secured a major upset by beating hosts Barcelona 2-3 in the Europa League quarter-finals.

Two goals from winger Filip Kostic and a third to Rafael Borré put Frankfurt 4-1 ahead on aggregate in the second leg, but the Germans had to weather a late Barcelona storm to secure their spot in the final four.

Serbia international Kostic opened the scoring for Frankfurt in the fourth minute via a penalty after Jesper Lindstrom was brought down by Eric Garcia in the box.

That was followed by a thunderous strike by Borré in the 36th minute from 30 yards out.

Kostic added a third in the second half to give the club a much-needed cushion as the Catalans fought back in the game's dying stages at Camp Nou.

Despite having 75 per cent of possession, Barcelona registered fewer shots and major chances throughout regulation time, including missing a handful of opportunities through Pierre-Emerick Aubameyang.

With an unhappy home crowd at their back, the fallen giants were forced to claw two desperate goals back in stoppage time through Sergio Busquets and Memphis Depay, who converted a penalty in the 101st minute after Frankfurt's Evan N'Dicka was sent off with a second yellow.

But their late surge was not enough to force extra time. Frankfurt, home to Socceroos midfielder Ajdin Hrustic, held on to win the game 3-4 on aggregate and claim their first win over the La Liga side in front of a raucous travelling contingent.

«I am speechless,» Frankfurt goalkeeper Kevin Trapp said.

«Nobody expected this, to be honest. Everyone expected us to suffer here.

»We needed to take our chances and today, we were very efficient. We are in the last four and we want to get as far as possible. We showed we don't have to hide from
