Real Madrid have urged their supporters not to take to the streets on Thursday night if they win the Spanish league title.
Zinedine Zidane's side will be champions if they beat Villarreal and the tradition in such moments is for supporters to congregate at the city's Cibeles fountain.
But in a statement issued on Tuesday the club said: "With just two matchdays of the LaLiga season to be played, both our team and FC Barcelona have a chance of being crowned champions.
"In the event that Real Madrid are crowned champions, our players will not visit the usual points of celebration, in particular, the Plaza de Cibeles and we therefore also ask our club members and supporters that, in the event that we secure the title, they did not gather in these places.
"In this regard, all of us must make a contribution, as has been the case to date, and show the utmost responsibility to avoid the risk of contagion."
There have been 28,409 deaths from Covid-19 in Spain.
The country came out of a three-month state of alarm last month but a recent upsurge in new cases in certain areas has led to some localised restrictions being imposed again.
"Real Madrid feels the duty to issue this important call in a show of utmost responsibility and with the firm belief that any possible triumph involving our team must not give rise to a massive backward step in the battle we are all waging against this pandemic," the statement added.
