Tottenham midfielder Harry Winks denies the squad is "too nice".
But Winks, whose side bounced back after a dismal defeat to Sheffield United, said: “I wouldn't say we're too nice, no.
“We've been on the receiving end of each other's critiques before after some defeats or games when we haven't been right. We've told each other.
“After the game against Sheffield, it wasn't a pretty game, it wasn't a good game to be involved in and we had some words to say to each other.
“The most important thing we can do is show it on the pitch. We can say stuff in the changing rooms and in team meetings.
“But we have to show it on the pitch and I think this was a step in the right direction."
Winks also praised Mourinho for helping Spurs to develop a strong mentality as they try to reach a European spot.
He said: “Do we have a strong mentality? I think so, yeah. Especially when the manager's come in, we've got some positive performances and results.
“Our problem has really been consistency and that's something we have to work on going forward.
“If we want to challenge for the Premier League or be around the top four, it's important we have consistency. That's really been our problem this season."
