Tottenham Hotspur boss Jose Mourinho admits it has become more difficult to communicate with players in today's game.
Mourinho, 57, has won it all across a long career in Portugal, Spain, England and Italy.
Speaking before Thursday's clash with Bournemouth, Mourinho said: "I think, overall, if I compare for example my times as an assistant coach, many years ago – Barcelona, Porto, 25 years ago or so – the players used to be together all the time.
"No X-Box, no PlayStation, no social media. It was the beginning of mobile phones but the players used to spend all the time together, even when you go to hotels or something.
"The players would be together all the time and it was easier for them to develop a certain intimacy, confidence, trust and develop a certain dynamic in the group. In this moment you can imagine – and it's not just football players but everybody – people are, it's a different way to interact.
"For example you are in a hotel and every player has his own bedroom in the hotel. The players go there and they're not alone. They're on Zoom and Facetime with friends and family. They're on social media. They're "together" playing some X-Box or PlayStation but to be together they don't need to share the same room or space.
"I think it's just a society thing that the interaction is different. I think probably at a personality level you don't get such open communication as you had before."
