Tottenham have sacked manager Nuno Espirito Santo after only four months in charge.
Spurs have lost five of their past seven league matches, including Saturday's defeat by Manchester United.
"I know how much Nuno and his coaching staff wanted to succeed and I regret that we have had to take this decision," said managing director of football Fabio Paratici.
The Portuguese, 47, was named Spurs manager on a two-year contract in June after four years at Wolves.
"Nuno is a true gentleman and will always be welcome here. We should like to thank him and his coaching staff and wish them well for the future," added Paratici.
Tottenham said a decision on who will succeed Nuno will "follow in due course".
Spurs, who were booed off following the 3-0 home loss to United, started the season strongly and after winning their first league three matches, Nuno was named Premier League manager of the month for August.
However, the results started to suffer. Despite wins over Aston Villa and Newcastle in October, there were defeats against Chelsea, Arsenal, West Ham and Crystal Palace, as well as a Europa Conference League loss at Dutch side Vitesse Arnhem.
