Robert Lewandowski v Russell Martin
Norwich defender Martin and central defensive partner Gordon Greer helped Scotland keep a clean sheet in their friendly win in Warsaw in March but Lewandowski was missing through injury.
The Bayern Munich attacker took his international tally to 23 with four goals against Gibraltar last month and set up Poland’s second against Germany on Saturday thanks to his strength, skill and awareness.
Kamil Glik v Steven Fletcher
Torino captain Glik is a no-nonsense centre back who carries a threat at set-pieces. His aerial ability will help against Sunderland attacker Fletcher, who is renowned for his headed goals. Scotland will need Fletcher to hold up the ball well, as he did against Georgia on Saturday, if their counter-attacking game is to work in Warsaw.
Lukasz Pisczek v Ikechi Anya
Anya sat out training last night, however, Strachan will be hoping he is fit to play a part as his pace and direct running are among Scotland’s best attacking weapons, especially away from home, as evidenced by the Watford winger’s goal against Germany. Poland right-back Piszczek will know what to expect after Anya’s goal at the home of his club, Borussia Dortmund.
