Manchester United boss Jose Mourinho has criticised Zorya Luhansk fans for throwing a firecracker at Sergio Romero.
Romero quickly stamped it out in his penalty box, but Mourinho expects UEFA to take action against Zorya over the first-half incident.
"The support was beautiful and they don't need that to make it more beautiful because they make it dangerous for the goalkeeper," said Mourinho.
"You don't need these things. Maybe UEFA are not happy and take some money from Zorya, and Zorya don't deserve that."
