To win a game is to nullify your opposition while exploiting your own strengths.
Correspondingly, against Wigan, it meant realising the mistakes that had led to us losing it last time (slow start, no penetration, lacklustre break-away defending) and denying them the opportunity to employ their favoured tactics (6 across the back, 3 men hounding Bale/Dempsey/Defoe), while closing them down effectively and maintaining concentration for the full ninety minutes.
We were given the perfect start: a ludicrously lucky goal that would have forced Wigan to come out and play, stretching the game and allowing us to create more opportunities in our favor.
We then did what no top team should ever do: concede directly after scoring. We switched off at a corner, Jan casually lost his man and Boyce scored, meaning we held the lead for a grand total of one minute.
We lost concentration when we most needed it. And then, Wigan could play the way they liked: defensive and reliant upon break-aways.
So we failed the first 'What have we learned' test. We didn't concentrate, again, despite being punished for it in the disastrous home game.
Having done that, though, we could at least have sprung into action at the start of the second half, getting at Wigan with quick, purposeful passing when they were still trying to take the lead. But we didn't. We gave the ball away, made stupid errors and allowed them time and space on the ball outside our area. They scored. 2-1. Now they could sit back to their heart's content. So again, we failed to learn from last time: don't let Wigan take the lead.
Finally, having made consecutive errors of judgement, we compounded them by putting in an utterly inept attacking display, devoid of threat or purpose. We were petulant ,conceded stupid free-kicks and played at a snail's tempo: perfectly suiting Wigan. Again, a stupid thing to do.
In summary, we learned nothing from the last time we played Wigan. They were no better than they were at the Lane. We were just equally as bad as we were then.
