Mourinho was sacked earlier this week after guiding the Pensioners to only four wins in their first 16 league matches, suffering nine defeats and picking up only 15 points.
Holland guided the Blues to a 3-1 triumph over Sunderland on Saturday, thanks to goals from Branislav Ivanovic, Pedro and Oscar, but will now step down from his role as caretaker coach following the appointment of Guus Hiddink.
Speaking after the victory, Holland has revealed that he’s set to go out for dinner with former boss Mourinho.
“Jose has invited me out for a meal next week and our relationship is excellent,” Holland said, as per the Daily Mail.
“I think he would recognise that I gave him everything. I would also recognise that not only is he an exceptional coach, he’s an exceptional person.
“But that’s not the guy you see very often. You see the competitor in front of the lens, before and after the football match.
“I’ve been able to get to know him a bit deeper than that, and he’s an exceptional person that it’s been a privilege and a pleasure to work with.”

Victory takes Chelsea up to 15th in the table, and four points clear of Swansea City, who occupy the third relegation spot.
With upcoming fixtures against Watford and out-of-sorts Manchester United, Blues fans will be hoping that Hiddink can steady the ship and guide the Pensioners out of troubled waters.
