Wojciech Szczesny was substituted due to discomfort in his chest as Juventus edged to a 1-0 home win over Sporting Lisbon in the first leg of their Europa League quarter-final. The Juventus keeper was replaced by Mattia Perín just before half-time, with teammates calling to the bench for a substitution after Szczesny was seen holding his chest. The Poland international left the field in tears, but Juventus later tweeted that he was “doing well” after undergoing an initial check. After the match, Szczesny said he had experienced breathing problems on the pitch but that he had been cleared by doctors. “We did medical check, it’s all good,” the 32-year-old said. “I was worried, I was not able to breathe but now I feel good. The tests confirmed there’s no problem”. Federico Gatti scored the only goal of the game at the Allianz Stadium, the defender firing home after a penalty-area melee to give Max Allegri’s side a narrow advantage for the second leg in Portugal. The winner of that tie will face either Manchester United or Sevilla, who drew 2-2 at Old Trafford in their first leg. Florian Wirtz hit an 82nd-minute equaliser as Bayer Leverkusen salvaged a 1-1 draw against visitors Union Saint-Gilloise, who eliminated Union Berlin in the last 16. Xabi Alonso’s side will be relieved to have avoided a surprise defeat, but face a tough test in Belgium to reach the semi-finals. Union SG took the lead early in the second half through Victor Boniface’s clinical finish. The hosts spurned chances to level, with Jeremie Frimpong heading wide from close range, before Wirtz found the bottom corner from Sardar Azmoun’s pass. Azmoun then put a shot just wide in stoppage time as it ended all square. Earlier, Mats Wieffer scored a second-half winner to earn Feyenoord a 1-0 home victory over Roma in the first leg of their quarter-final as Lorenzo Pellegrini hit the post with a first-half penalty. That spot-kick had been conceded by Wieffer, for a pull on Abraham, but the midfielder made amends in the 53rd minute. After an incisive run and cut-back from winger Oussama Idrissi, Wieffer scored with a bouncing half-volley from outside the box. José Mourinho’s side, who are chasing a top-four finish in Serie A, suffered two serious injury setbacks as both Paulo Dybala and Abraham were forced off. “Of course, we had opportunities. But football is not about chances. It’s about scoring goals,” said a rueful Mourinho afterwards.
