Writing in the Daily Telegraph, Will Greenwood believes Heineken Cup hopefuls must hold their concentration for the full 80 minutes.
"It’s called Fergie Time. Manchester United may not have managed it in the Champions League this week, but Sir Alex Ferguson’s sides so often manage a great escape when it comes to the final minutes. They understand that as the sands of time run out, the weight of expectation can all but crush those in the lead.
"Rugby is no different, even if the red zone comes after 80 minutes. The losing side have a desperation that makes them dangerous, and if you want proof of what can happen, then you only need to look at the first two rounds of the Heineken Cup when games and fortunes have turned around in ‘Fergie Time’.
"Go back a few Sunday afternoons, and Glasgow were behind at home to Bath. The clock ticked on, and they were going nowhere offensively. Fly-half Duncan Weir pulled back in the pocket for a speculative dropped goal. It was half charged down and if you had paused the moment there you would have seen there was no way Richie Gray, the Glasgow second row, should have got to it first. But that’s the beauty of ‘Fergie Time’ – it warps reactions and changes perceptions."
