UEFA insists there is "no reason to prepare a Plan B" for the final eight of the Champions League in Lisbon in August despite several suburbs of the city preparing to go back into lockdown as COVID-19 cases climb again.  

The European soccer body's president Aleksander Ceferin said he saw "no need for a Plan B" after discussing plans with Portugal's Prime Minister Antonio Costa, although UEFA recognized that organizing the tournament represented "great challenges."

"During the meeting, all parties underlined they are fully committed to working together in a collaborative manner in order to deliver a successful event in Lisbon," UEFA said in a statement. 

From Wednesday, 19 neighborhoods on the northern edges of Lisbon will go back into lockdown. 

Gatherings will be limited to a maximum of five people in these areas, compared to 10 people in the wider Lisbon area and 20 people across the rest of Portugal. 

The measure will be in place from July 1-14 and will then be reviewed. 

UEFA in June announced that the latter stages of the Champions League would be staged exceptionally as a straight knockout competition from the quarter-finals onwards with all matches in Lisbon. 

The final eight is due to begin with the first quarter-final on August 12, with the final scheduled for August 23. 

Atletico Madrid, Paris Saint-Germain, RB Leipzig and Atalanta all qualified for the quarter-finals before the competition was suspended in March. 

The remaining last 16, second legs are: Juventus v Lyon; Manchester City v Real Madrid; Bayern Munich v Chelsea and Barcelona v Napoli.
