Chelsea's Champions League last-16 first leg against Atletico Madrid will be played in Romania because of coronavirus travel restrictions.
La Liga leaders Atletico were due to host the game on Tuesday, 23 February at 20:00 GMT but it will now be played at the Arena Nationala in Bucharest.
Spain has placed restrictions on travellers from the UK, where a new variant of Covid-19 is present.
