Manchester United boss Jose Mourinho has criticised the pitch for his side's Europa League match against Russian side FC Rostov on Thursday.
Rostov, fifth in the Russian Premier League, play at the Olimp-2 which was built in 1930 and has a capacity of just over 15,000.
Ahead of the last-16, first leg tie, Mourinho said: "It's hard for me to believe we are going to play on that field - if you can call it a field.
"I don't know which team to play."
Mourinho drew comparisons with the quagmire that saw United's pre-season friendly against Manchester City in Beijing called off.
