Tottenham manager Jose Mourinho says he is “disappointed” after three of his players breached coronavirus rules by attending a party over Christmas.
A picture on social media showed Argentina forward Erik Lamela, Spain defender Sergio Reguilon and Argentina midfielder Giovani lo Celso at a party.
“We are not happy – it was a negative surprise for us,” said Mourinho.
In a statement, Tottenham said they were “extremely disappointed” and “the matter would be dealt with internally”.
West Ham reminded Argentina forward Manuel Lanzini, who also attended the party, of his responsibilities.
Lanzini apologised in a tweet on Saturday, saying he made a “bad mistake”.
“I take full responsibility for my actions,” he said. “I know people have made difficult sacrifices to stay safe and I should be setting a better example.”
Lamela and Lo Celso were not involved in Saturday’s 3-0 Premier League win at home to Leeds, while Reguilon, who joined from Real Madrid in September, was on the bench.
“I gave an amazing gift to Reguilon – Portuguese piglet,” Mourinho said. “Amazing for Portuguese and Spanish. I was told he would spend Christmas on his own. He was not alone as you could see.
“We, the club, feel disappointed because we gave the players all the education and conditions. We know what we are internally. We don’t need to open the door to you and let you know what is going on internally.
“What are going to be the consequences and how deeply we approach that negative surprise? I feel disappointed.”
