Steve Cotterill tipped Marko Futacs to trouble Championship keepers with his ‘hammer’ shot.
And the Pompey boss insisted: It was a ‘no-brainer’ signing.
Cotterill made Futacs his ninth summer addition last week after sealing a one-year deal with another year’s option for the 21-year-old.
Futacs had impressed while on trial with Pompey and scored in the 4-0 friendly win over Swindon last week.
The 6ft 5in powerhouse trained before and after the weekend draw with Cardiff.
Cotterill believes the former Werder Bremen man will add something to his now healthy list of striking options, including the likes of Dave Kitson and Kanu.
Futacs spent last season on loan at German second division side FC Ingolstadt 04 before leaving Bremen in the summer, with a year remaining on his deal.
Cotterill likes what he has seen of the striker so far. And he feels getting a player of his potential on a free transfer represents excellent business.
Now the Blues boss is looking forward to seeing what damage Futacs’ power can do to opponents.
Cotterill said: ‘Hopefully he will do okay. He has been with us on trial.
‘He’s one of them ones we ended up getting on a free transfer, so we will wait and see how he develops over the coming months.
‘He’s been with us for about a week and has been at Werder Bremen so has got a decent pedigree. He’s a big, strong boy and has an absolute hammer of a left foot.
‘We got him on a free transfer and it was a no-brainer, really. We’ll have to see what we can get from him.
‘He was attached to Werder Bremen. Let’s just say we were lucky to get him on a free transfer.’
