BILBAO — Manchester United coach Ruben Amorim admitted he can’t explain why fans and the board still back him despite the team’s worst Premier League form in 50 years. United have lost their last eight league games but reached the Europa League final, offering hope. Amorim said the club’s problems run deeper than a single trophy and stressed that winning the final could help build a brighter future, though it won’t erase ongoing challenges. Key players are returning from injury ahead of the clash with Tottenham, boosting United’s chances.
