Arsenal hammered 4 goals past a hapless Slavia Prague in their 2nd leg of the quarterfinal clash in the Europa League. Nicolas Pepe and Bukayo Saka scored a goal each while Alexandre Lacazette netted a brace on a perfect night for Arsenal and Mikel Arteta as they won 5-1 on aggregate. Arsenal will now play Villarreal in the 2nd semifinal as it will be a reunion of sorts with former Gunners boss Unai Emery. Meanwhile, Manchester United also entered the semifinals of the Europa League after an easy 2-0 win over Spanish club Granada in the 2nd leg of their quarterfinal tie. Edinson Cavani opened the scoring in the 6th minute and Granada contributed with an own goal in the losing cause as Ole Gunnar Solskjaer's men won 4-0 on aggregate. They now play Italian giants AS Roma in the semifinals.
