Inter Milan winger Ivan Perisic was in fantastic form for Croatia in their 2-1 win over England in their semi-final clash on Wednesday, during which he scored a goal and provided the assist for the extra-time victor.
United do, of course, have a number of players still on worldwide duty at the World Cup and there are a host of others whose involvement earlier in the competition means they will also join up at a later stage.
"The team improved a lot in relation to previous appearances".
United will be without the likes of Phil Jones, Marcus Rashford, Jesse Lingard, Ashley Young and Paul Pogba during the tour after their participation at the World Cup in Russian Federation.
"Gareth Southgate and [assistant manager] Steve Holland, if I was the FA, if i was in charge, no doubt that I would keep them in the job and I would give them the chance to take the team to the next Euros, eventually to the next World Cup".
"The players and the squad, everybody involved in the World Cup, have a reason to come back home with pride after giving everything and making the country proud".
It prompted a glowing assessment from Mourinho, who added: "It's a great achievement for a country where the league is a minor league and the majority of the players don't player in Croatia but overseas".
"So for them to go back to their country and take a nation like Croatia to the World Cup final is something wonderful".
