Barcelona and Atlético Madrid both rallied from two goals down in a frantic 4-4 draw in the first leg of their Copa del Rey semi-final at the Estadi Olímpic Lluís Companys.

Atlético took an early lead with goals from Julián Álvarez in the first minute and Antoine Griezmann in the sixth, but the home side had levelled the game by the 21st minute thanks to two goals two minutes apart from Pedri and Pau Cubarsí.

Barcelona took a 3-2 lead into half-time after Iñigo Martínez scored in the 41st minute and Robert Lewandowski increased the lead in the 74th. The visitors pulled closer through Marcos Llorente in the 84th minute and Alexander Sørloth got the equaliser from close range in the third minute of stoppage time.

The second leg will be at Atlético’s Metropolitano Stadium will be in April and the winner will play either Real Madrid or Real Sociedad, who will play the first leg of their tie on Wednesday.

Inter secured a commanding 2-0 victory at home against Lazio, with Marko Arnautovic producing a dazzling strike that sent them into the Coppa Italia semi-finals.

The Austrian striker produced a goal-of-the-season contender six minutes before half-time, firing home a perfectly struck volley that flew into the net from outside the box after a corner was headed clear. “What matters for Inter also matters for me. The most important thing is winning the match, and we are very happy,” Arnautovic said as he downplayed his spectacular goal.

Lazio pressed in the second half, with Gustav Isaksen nearly scoring just before the hour mark from a tight angle, but the Inter goalkeeper, Josep Martínez, kept out the attempt with his foot.

Hakan Calhanoglu sealed the win for Inter in the 77th minute from the penalty spot, sending the Lazio goalkeeper, Christos Mandas, the wrong way after Samuel Gigot fouled a charging Joaquín Correa. Inter will face Milan in a two-legged encounter in the semi-finals in April.

“Last season we beat Milan many times, we will be ready and we will think about it when the match arrives,” the Inter midfielder Piotr Zielinski said. Juventus will host Empoli on Wednesday, with the winner set to face Bologna in the other semi-final.

The third tier side Arminia Bielefeld stunned the Bundesliga club Werder Bremen with a 2-1 victory at Bielefelder Alm in a major upset to reach the DFB Pokal semi-finals.

The home side, who have now eliminated three Bundesliga clubs in a row after wins over Union Berlin and Freiburg in the previous rounds, went in front after Werder lost possession in their own half and Marius Wörl curled in a shot after 35 minutes. The visitors were two goals down six minutes later when the defender Julián Malatini tried to clear a cross but the Argentinian turned the ball into his own net.

Werder cut the deficit in the 56th minute with Oliver Burke’s effort giving them hope, and they hit the crossbar in stoppage time through Amos Pieper’s header. The holders, Bayer Leverkusen, and VfB Stuttgart had already advanced to the last four. RB Leipzig host Wolfsburg on Wednesday for the last semi-final spot.
