JOIN USGoal-scoring machine Gerd Mueller was unkindly nicknamed 'short, fat Mueller' during his career, now Germany's latest hot-shot star Thomas Mueller has been dubbed 'El Flaco' -- the Skinny One -- by Argentina legend Maradona.
Mueller claimed the first hat-trick of these World Cup finals in Monday's 4-0 drubbing of Portugal in Germany's Group G opener in Salvador.
The Bayern Munich star, 24, is normally deployed as a winger or attacking midfielder and has only made rare appearances as striker for either club or country.
But the gangly Mueller repaid the faith of head coach Joachim Loew with an impressive display as a striker against Portugal, which led to Maradona -- who almost singlehandedly inspired Argentina to the 1986 World Cup trophy --dubbing him 'El Flaco'.
"He has no muscles, but today he tore them (Portugal) apart," an impressed Maradona, who knows a thing or two about goal-scoring, told Venezuelan television.
The goal-scoring exploits of stocky 1970s star Gerd Mueller are legendary amongst Germany fans, but his younger namesake currently has his football-mad country swooning.
The 68-year-old Gerd -- also nicknamed 'Das Bomber' -- retired after scoring West Germany's winning goal in the 1974 World Cup final against the Netherlands.
He finished his career with an incredible 68 goals in 62 internationals and the younger Mueller is producing similar impressive statistics with 20 goals in 50 internationals.
"The lad's fast, he's got a good technique - he's going to be a great player," Gerd Muller said.
With eight World Cup goals now to his credit, the younger Mueller out-shone Portugal's World Player of the Year Cristiano Ronaldo.
While the Portuguese captain is renowned for his personal grooming and showing off his finely-honed torso in his goal celebrations, Mueller has a touch of the boy-next-door.
"It's his unorthodox playing style that characterizes Thomas Mueller," ex-Germany captain Oliver Kahn told braodcasters ZDF.
"Sometimes he doesn't know himself exactly what he's going to do. There's a lot of intuition involved, he always knows where he has to run.
"His body language is very important, he makes a strong impression and says 'we want to be world champions' -- I like that."
Mueller's self-confidence was clear as he picked up where he left off at the 2010 World Cup -- his break-through tournament -- when he finished joint top-scorer to claim both the Golden Boot and best young player awards in South Africa.
"He's a light-hearted, cool guy," enthused German FA president Wolfgang Niersbach.
"He says before the tournament that he would again like to be the World Cup's top-scorer -- then he goes and scores three goals.
"He's relaxed and determined at the same time."
Mueller started against Portugal ahead of Germany's all-time top-scorer Miroslav Klose, 36, with the Lazio star just one short of now retired Brazilian great Ronaldo's record of 15 World Cup goals.
But Loew said Mueller's unorthodox runs are an asset which leaves defences guessing the Bavarian's next move.
"He is a very unorthodox player and you can't really predict his lines of running, but he has one aim and that is 'how can I score a goal?'", said Loew.
"That makes him so dangerous, especially in the box."
