Lawrence told the Western Mail.
"I'm very pleased about this because Tomasz has trained with us and he certainly looks the part. He has got a good pedigree, he is versatile - and he is very keen on coming to Cardiff."
The first application for his work permit was refused, Lennie explains
"Our original application for a work permit was turned down because players from countries outside the EC need to have played 75 per cent of internationals in the last two years - Tomasz had played in 68 per cent. I put forward a case based on Tomasz's playing background and that Poland will be coming into the EC next year.
"I also explained why Tomasz missed the internationals that he did and we got the work permit. We will fly Tomasz over from Poland today so he can resume training with us. He might play Saturday but at the moment I would say he would be a substitute."
Excellent news, it looks like we have ourselves a third summer signing and an international to boot. Klos can play centre back or right back. He is 30 and signs on a free as his contract with German club Kaiserslautern has ended.
On a trivial note I ws cruelly exposed yesterday when I forget about Matt Brazier and Fan Zhiyi being recent City players with the letter "Z" in their name. In the not too distant past we had Derek Brazil and Mark Aizlewood as well. OK then, have we had a Polish international playing for us before?
