Poland boss Adam Nawalka is prepared for a physical encounter with Scotland

Poland manager Adam Nawalka is prepared for a physical encounter with Scotland at Hampden on Thursday.

The build-up to Thursday's European Qualifier has been dominated by Robert Lewandowski's goalscoring form and his complaints over a challenge by Gordon Greer in last year's 2-2 draw in Warsaw.

Lewandowski called for protection at Hampden after being hurt in what he described as a "brutal" tackle by the Brighton defender, who caught him high with his studs as he went to block a shot, just as the whistle blew for a previous infringement.

When asked about the controversy, Nawalka said: "Of course we need to be prepared for a good fight and for aggressive play.

"In the final stages of the qualifiers we need to be prepared for this but also we hope that skills will be more important. We also hope we will be in control of the game and play the ball as we get it."

Nawalka side-stepped another question about Scotland boss Gordon Strachan's comments earlier when he stressed that Poland had committed 30 more fouls than his side during their eight qualifiers.

"We are certainly anticipating a very difficult game with a lot of energy and fight," he added.

"We have our game plan, we feel we have prepared well mentally and tactically."

Nawalka stressed that he respected the creative attributes of Scotland, who also won in Warsaw last year, during a friendly.

"Scotland do very well as a team," he said. "They play collectively and are disciplined and also creative.

"They don't play in a traditional, physical British way. They don't play long balls, they can be very constructive in attack.

"They have a very advanced European game and when you look at it from a global perspective, you can see it's a very difficult opponent. We need to respect them and we do."

While much of the focus has been on Lewandowski, who has scored 12 goals for his club in four games, Nawalka insists he has other top performers other than the Bayern Munich star.

"Lewandowski is the best centre-forward in the world for me, of course," Nawalka said. "He is number one. He's the best striker in the world.

"Of course Robert is a very important player in our team. He's the key player and has a lot of different strengths. He has leadership qualities and gives a lot of energy to other players.

"However a lot of our team members do their job and do the best they can and they are very important. You can see the atmosphere in the team is very good.

"They keep improving and that's the foundation for the future of our team."
