Things could get very, very awkward between Jose Mourinho and Gary Neville, Jamie Redknapp as well as Graeme Souness after he joined the Sky Sports team as a pundit.
The ex-Chelsea and Manchester United boss has joined Sky Sports as a pundit for the new season and it's set to be an interesting encounter following his past comments on the trio.
During his first spell at Stamford Bridge, Mourinho trolled Redknapp by sarcastically saying he has a "brilliant football brain."
He also said: "Jamie stopped playing a couple of years ago and in two years he forgot every single thing he did on the pitch."
Mourinho took a swipe at Neville for his nightmare spell as Valencia head coach.
"In England, former top players, amazing in front of the screen. They go to football clubs and after two months, goodbye, let's go home," he said.
Souness has also had a verbal battering off Mourinho, who once said: "A pundit is not honest if they cannot forget their colours or if they try to hide the truth from their audience. It's not my fault if their managerial career was very poor."
The Portuguese will make his first studio appearance on Sunday for the Premier League showdown between Manchester United vs. Chelsea.
In a statement, he said: "The Premier League is a special competition for me, one that takes so much hard work to win and you just can't take your eyes off the matches every week.
"Sky Sports is the home of the Premier League and it's a pleasure for me to join this team and help to understand and explain what happened in each match.
"Football is a huge passion, it means so much to the fans, and I look forward to being part of the Premier League with them until I return to my place on the touchline."
