Former Manchester United midfielder Nemanja Matic has labelled Andre Onana as "one of the worst goalkeepers in the club's history". Serbian Matic, 36, was responding to Onana's comments about United being "way better" than French club Lyon as the two sides prepare to meet in the Europa League quarter-finals on Thursday. Onana then posted on social media, denying he was being disrespectful. "I respect everybody," said Matic, who joined Ligue 1 side Lyon in 2024. "But when you are one of the worst goalkeepers in Man United history, you need to take care what you're talking about. "If it was [Edwin] Van der Sar, [Peter] Schmeichel or [David] De Gea saying that, then I would question myself. But you need to have cover to say something like that." The Europa League is the final opportunity for Ruben Amorim's side - currently 13th in the Premier League - to save a disappointing season. Matic made 128 appearances for the Red Devils between 2017 and 2022 while Onana signed for £47.2m from Inter Milan in 2023. "I would never be disrespectful to another club. We know that tomorrow will be a difficult game against a strong opponent," Onana said on X. "We focus on preparing a performance to make our fans proud. "At least I've lifted trophies with the greatest club in the world. Some can't say the same."
