Northern Ireland need to come out of their shell in today’s Euro 2016 Group C clash against Ukraine if their first major tournament appearance for 30 years is not to end in an anti-climax.

Both sides are promising a more attacking approach than in their opening games, where the Northern Irish went down 1-0 to Poland and Ukraine were dispatched 2-0 by Germany.

The Ukrainians can at least take heart from the fact that they held the world champions to 1-0 until substitute Bastian Schweinsteiger scored in stoppage time. They also created chances of their own, at one point forcing a spectacular goal-line clearance.

Northern Ireland, by contrast, were a shadow of the side that qualified unexpectedly as winners of their group. They never looked like scoring against Poland and striker Kyle Lafferty, a lonely figure up front, lamented: “We didn’t turn up today.”

Coach Michael O’Neill has said the squad was devastated by the death of a 24-year-old fan, Darren Rodgers, in a fall from a seafront railing in Nice early on Monday, and wants to make today’s game a “fitting tribute”.

With Germany waiting as their next opponents, the Ukraine fixture is Northern Ireland’s best and perhaps only chance to pick up points.

“We have to be more aggressive against Ukraine,” defender Jonny Evans said.

Ukraine have strong attacking options of their own, through wingers Andriy Yarmolenko and Yevhen Konoplyanka.

“We are still thinking about the starting line-up. There is time to choose the right tactics for the game but one thing is clear: we will attack,” assistant coach Andriy Shevchenko said.

“At the same time, we need to be accurate, especially at the back.”
