Scotland v Poland: Robert Lewandowski 'best in the world'

Lewandowski has netted 10 times in Group D but did not score against Scotland last October

Scotland will face the world's best striker in Robert Lewandowski when they take on Poland on Thursday, according to visiting coach Adam Nawalka.

Bayern Munich's prolific forward is expected to start up front for the Poles in the Euro 2016 Qualifying Group D match in Glasgow.

Lewandowski has scored 12 goals in his last four games, including five in one match against Wolfsburg last month.

"For me, he is the number one," said Nawalka.

"He's the best striker in the world. I know him personally, I know his skills. I can count on him."

Lewandowski's recent scoring exploits have taken his tally in Germany's Bundesliga above 100 goals, while he has netted 29 times in his 70 appearances for Poland. He is the top scorer in Group D with 10 and Poland, second in the table, are on course to progress to the finals in France.

The aggressive nature of a challenge by Gordon Greer on Lewandowski, which went unpunished in the sides' last meeting - a 2-2 draw in Warsaw - has taken centre stage in the Polish media in the build-up to the Hampden fixture.

It has prompted suggestions from within the Polish camp that the Scots will be overly physical, but the head coach says his team are up for the challenge.

"We need to be prepared for aggressive play," added Nawalka.

"I hope in these finals stages of qualification that skills will be more important and we hope to be in control of the game and play the ball as we like it.

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

"We have our plan and we have our tactics."

While Lewandowski is seen as the focal point of the Poland team, Nawalka does not see Scotland as having the same individual brilliance.

"The key asset of the Scotland team is the fact they play collectively - they are very disciplined," he explained.

"They are also creative. They do not play long balls, they can be very constructive offensively.

"They play an advanced European game and when you look at it from a global perspective you see that the whole team is a very difficult opponent and we need to respect them."
