Erik ten Hag has branded Cristiano Ronaldo's decision to leave Old Trafford during Manchester United's 1-1 draw with Rayo Vallecano as "unacceptable."

Ronaldo started the match but was substituted at half-time. He was pictured leaving the stadium before the full-time whistle.

"It is unacceptable for everyone," he told Viaplay Sport Netherlands. "I am telling them it's unacceptable. We are a team. A squad. Until the end we stay together."

Ronaldo would like to leave United this summer in order to continue playing in the Champions League. United have yet to receive an offer.
