I think Martin O’Neill’s solution to that conundrum will have a huge bearing on his team selection today and might even dictate the outcome of this crucial game for Ireland.
Is he going to do a job on Sweden’s superstar? Is he going to designate a midfield player to follow him around and try to stop him getting on the ball?
