Manchester United have also announced a call for peace ahead of Saturday’s Premier League match against Watford at Old Trafford.
Interim manager Ralf Rangnick, surrounded by players from both sides, held a placard marked “peace” in various languages.
Rangnick had spoken this week about the “very sad” situation in Ukraine following the Russian invasion of their neighbor, which has provoked international outrage.
“When I watch TV in the morning and in the evening I still can’t believe what I see there,” he said.
“This is just a bad situation and I really hope that politicians around the world can help alleviate this situation and end those kinds of things that are happening there.”
Manchester United this week terminated its sponsorship deal with Aeroflot, a Russian airline, due to the situation in Ukraine.
“We share the concerns of our fans around the world and extend our sympathy to those affected,” a spokesman for the group said.
