Jokanovic remains open-minded as you have to be in order to negotiate the nine-month Championship marathon which is the ultimate test of endurance, fortitude and mentality.
Jokanovic, who famously gave a teenage star in Ryan Sessegnon the platform to shine at previous club Fulham, commented: “I do not care about young and old. I will play players who are 16 years old or 36. I trust only the players.
“I do not treat young players like kids. I treat them like adult people. I worked with 12 players (at the start of training) and then brought 10 from the under-23s to cover the work.
“They can impress me and take it (the chance) and that is it. I am not scared of playing players who are young and old.
“You must be strong. The competition is tough and you need strong people and players. I do not care about age but personality. To compete in this competition without personality is impossible.
