The Republic of Ireland manager is confident his side won't be daunted by the task of trying to contain the Poland ace when the two nations meet in Group C on Monday
Michael O'Neill has described Poland's Robert Lewandowski as "one of the top two centre forwards in the world" ahead of Northern Ireland's Euro 2016 opener on Sunday.
Lewandowski scored 30 goals in 32 Bundesliga games last season as Bayern Munich retained their title in style, while also converting 13 times to help Poland book their spot at the Euros.
O'Neill rates the 27-year-old highly – putting him on a par with Barcelona's Luis Suarez – but is adamant his players will not be overawed when they meet in Nice.
