Liverpool had gone so close to a point after seeing Curtis Jones‘ booking upgraded to red midway through the first half after his challenge was reviewed by VAR.
But the main talking point was how Luis Diaz‘s opener was wrongly ruled out for offside due to what the Professional Game Match Officials Limited called a “significant human error” by VAR Darren England.
Summer signing Endo, who came on with Liverpool reduced to nine men, said: “At the end, a very tough game but there were 50-50 decisions in the game and yeah, it’s very difficult to play with nine players.
“But I wanted to get one point so I am very disappointed about it.
“I am just so proud of this team. I am just disappointed.
“We have to learn from this result and of course we showed our spirit, even though we faced difficult decisions we fought until the end.
“That’s Liverpool and always we have to try to win the game. We can learn from this game but we just keep going.”
Matip will be particularly desperate to win after his late own goal in the capital, but Endo says nobody in the dressing room is blaming the defender.
“Actually, he played an amazing game today so no-one can say something to him,” he told the club website.
“I am so proud of what he did today and I am so proud of what my team-mates did today.”
