The Republic of Ireland have produced an impressive defensive display to earn a goalless draw with Poland in Poznan.

The result means that Ireland are yet to concede a goal under Martin O'Neill's stewardship.

O'Neill's Boys in Green shaded a tight first half during which Stephen Kelly came closest to opening the scoring with a header that bounced just over the crossbar.

Poland improved after the interval, but they were unable to break down a rigid Irish backline as John O'Shea excelled, making a number of vital blocks to frustrate the lively Jakub Błaszczykowski.

David Forde was rarely called upon, but the Millwall goalkeeper did make a sharp save to keep out Lukasz Szukala's firm header.
