Kevin O’Brien feels Ireland have a lot to prove against ‘biggest enemy’ England

England head into the final ODI with an unassailable 2-0 advantage

Kevin O’Brien is aware Ireland must improve their top-order batting if they are to claim a consolation victory over their “biggest enemy” England in the final one-day international at the Ageas Bowl.

In the first two Royal London series matches, Ireland have been six wickets down with fewer than 100 runs on the board, relying on twin half-centuries from newcomer Curtis Campher to carry them to respectable totals.
