Kacaniklic believes the Cottagers' victory over Roberto Martinez's men shows they are slowly improving and leapt to the defence of his manager, hailing the work he has done for the club.
"He is always encouraging us so we are really happy for him and the team," the Sweden international told reporters.
"We are close. He is always out on the training pitch with us and wants to get involved.
"He is great. Everyone has got their own style but, as a player, you want to be able to speak to the manager and have confidence that you can speak to him."
