Tottenham defender Cristian Romero admits he's trying to be more disciplined in games.
Romero concedes he's collecting too many cards.
He told Sky Sports: "I know it is an aspect of my game I need to work on and polish up a bit and improve.
"I was aware that I was picking up too many cards so I set out to work on it.
"Maybe it is down to my style of play, on many occasions protesting too much for clashing with someone, so in situations like this I think I've improved a great deal."
