Poland: Talismanic defender Kamil Glik will face a late fitness test on a shoulder injury, though the fact that he stands any chance of featuring is a testament to him, with it initially thought that the injury would keep the Monaco man out of the tournament.
Senegal: Defender Saliou Ciss will play no part for Senegal after being sent home due to his failure to recover from an ankle injury. Caen's Ablaye Mbengue has been called up to replace Ciss.
Poland striker Robert Lewandowski:
"I played less games this season, which means I'm less tired. I hope this freshness will show.
"This time the preparations have been personalised, catered to what an individual player needs.
"I am not sure how many good opportunities I will have. But when I am doubled up on and fouled, it frees up space for my team-mates and we'd like to take advantage of this.
"I want my hunger for goals to be even bigger and bigger. And of course I hope more goals will come on the biggest stage - the World Cup."
Senegal boss Aliou Cisse on Sadio Mane:
"Sadio Mane is a unique player and he cannot be compared to any other Senegal player, even the major ones we've had in the past.
"And despite everything that has happened for him over the last two years, he hasn't changed - he's just as humble as he was when I first met him at the 2012 Olympics.
"Senegal isn't only Sadio Mane, though, he has a good team built around him and I think it should be a little plus for him that we're all behind him.
"He plays for one of the most iconic clubs, one of the best in Europe, and he's top-notch for them.
"He's absolutely unique because he is so unpredictable, that's what makes him great - he can make the difference with a pass or shot. He's already one of the best [players in the world]."
