Teams: Poland, Lechia Gdansk
Lubanski without a doubt. The problem is he never got to play in any big tournament while at 100%, but talk to anyone who has ever played against him and they will tell you that his speed and technique were light years ahead of virtually anyone, in the whole world, in the early 1970's. His injury, easy to treat nowadays was unfortunately damning back then.
Of course Deyna, Lato or Boniek (even Szarmach or Gorgon or Zmuda) did more for the Polish NT than Lubanski, because they suceeded in bringing home the hardware. But as an an individual player Lubanski was the best.
