The two Spurs players had to separate as they left the field at half-time after goalkeeper Lloris apparently criticized Sina for not doing his defensive job.
Furious Lloris pushed the South Korean international as players descended from the field and teammates were to lead Sina down the tunnel.
The pair then came out for the second half, they seem to have resolved their differences and hugged each other on a full-time whistle.
“It’s beautiful,” Mourinho said after the game. “If you want to blame someone for that, it’s me, because I’ve been critical of my boys, because they’re not critical enough of themselves, of each other.
“Something is very important for the team to grow and for that you have to look for each other and be strong personalities.
“A team of nice guys. The only thing I can win is the Fair Play Cup. It’s something I’ve never won, and I don’t care.”
“No problem at all”
A lucky own goal from defender Michael Keane was enough to trigger Tottenham to win over Everton in an otherwise difficult match at Tottenham Hotspur Stadium.
The Spurs, who have suffered a 3-1 defeat by Sheffield United, are now in eighth place in the table in their late bid for European football next season.
French international Lloris said the incident with Sina was just “part of football” and said they were moving on.
“There are no problems at all. There is a lot of respect between him and me,” he told BBC Sport after the game.
