England's Jack Wilshere has warned his team-mates not to underestimate Poland ahead of their World Cup qualifier at Wembley on Tuesday night.
The Three Lions need to win their final Group H clash to remain top and ensure automatic qualification for next summer's World Cup in Brazil.
Wilshere, however, is wary of the attacking prowess Poland posses with Borussia Dortmund duo Robert Lewandowski and Jakub Błaszczykowski and has urged caution.
The 21-year-old told the FA's official website: "They have some great players so it will be a tough game.
"We saw what Lewandowski can do last year in the Champions League; a lot of top clubs were after him so it shows how good he is.
"He's their main dangerman, we have to be tight on him and have to try and stop him. We must be up for it."
Wilshere, who is contention to play against Poland after being left out of the starting line-up against Montenegro last Friday, admits he is desperate to play for England in a World Cup.
He added: "It would be a dream come true [to qualify], especially after missing the Euros, that was a massive disappointment.
"But for me the World Cup is the biggest stage of all, to play for my country in a World Cup would be amazing."
