Chelsea v Porto Champions tie to be played in Seville

The matches will be played at Sevilla's Ramon Sanchez Pizjuan stadium, with the first leg on April 7 and the return on April 13.

Portugal was removed from the British government's list of countries on a travel ban red list earlier this month but anyone entering the UK from there is still required to self-isolate for 10 days.

It is just the latest European tie this season to be impacted by travel restrictions related to the pandemic.

Ironically the first leg of Chelsea's last-16 tie against Atletico Madrid was moved from Spain to the Romanian capital Bucharest.

Spain this week eased restrictions on people entering the country from the UK for certain reasons, including participants in high-level sporting events.

Both legs of the last-16 ties between Liverpool and RB Leipzig, and between Manchester City and Borussia Moenchengladbach, were switched to Budapest.

Meanwhile the two legs of the Europa League last-32 tie between Arsenal and Lisbon giants Benfica were played at neutral venues, in Italy and Greece.

Chelsea have already played at the Sanchez Pizjuan this season, beating Sevilla 4-0 in a group game in December.
