Thompson played a starring role in Melbourne’s 2-1 triumph over Perth Glory on Sunday, with his dazzling runs and expert vision helping set up numerous chances, including Carlos Hernandez’s 68th-minute match-winner.

National coach Pim Verbeek has used lanky striker Josh Kennedy and Scott McDonald as his preferred partnership up front for Australia, with the likes of Harry Kewell and Tim Cahill also used in forward roles at various times.

But Merrick felt there was room for 31-year-old Thompson, who has netted five goals this season, to be part of the World Cup squad.

“He’s played outstanding football and his work rate is phenomenal,” Merrick said of Thompson, who has scored 21 goals in 32 appearances in the green and gold.

“I think he’s in with a chance of the World Cup the way he’s playing, defending and attacking.

“His all-round game has improved out of sight and he’s as fit as he’s ever been.”

Merrick said the loss of fellow striker Danny Allsopp to Qatari club Al-Rayyan earlier in the season had seen Thompson lift to a new level.

“I think he’s definitely taken part of the role that Danny Allsopp used to fulfil,” Merrick said.

“He’s taken on a lot more responsibility and I think he’s maturing really well as a player.

“I think he’s just clicked with the players.

“He’s working hard, his attitude is fantastic and he’s motivated to play well with the Victory.

“I think the extension of his contract was a big plus for him and probably the opportunity to go to the World Cup is another motivation.

“But first and foremost he’s playing great for us.”

Melbourne have notched six wins from their past seven games to remain just one point adrift of Sydney and with several key players returning to the side they have their sights set on a top-two finish.
