England defender Gary Cahill has admitted that he does not know what to expect of Poland when the two sides meet in Tuesday's World Cup qualifier at Wembley Stadium.
The Three Lions can secure their place at next year's tournament if they win the Group H fixture, while the Poles have no chance of progressing.
"It's a bit nervy in the sense that we don't know what to expect," BBC Sport quotes him as saying.
"They can't qualify now, so are they going to go out relaxed and play care-free football? Are they going to change things up?
"It's hard to predict, but one thing we can be in control of is how we go out and play."
England earned a 1-1 draw in Poland in the reverse fixture nearly one year ago.
