THERE are few more exhilarating feelings in sport than an unlikely comeback and for those who watched Barcelona’s feat to overturn a four-goal first leg deficit on Wednesday night probably saw the best of them all.

Sport’s history has been littered with amazing turnarounds against the odds and each and every one rekindles memories of our own favourites.

Be it Liverpool’s Champions League triumph in 2005, Manchester City’s FA Cup comeback from 3-0 down at Tottenham to win 4-3 with 10 men a year earlier or Manchester United’s two goals in stoppage time to win the illustrious treble in 1999 – there have been many great turnarounds in football.

Fans in these parts will never forget that play-off triumph against Reading at Wembley in 1995.

The Royals were in the box seat for promotion after two goals in the first 12 minutes and when they were awarded a penalty just after the half-hour mark, Wanderers looked doomed.

But Keith Branagan saved Stuart Lovell’s spot-kick and there was renewed belief.

Two goals in the last 15 minutes sent it to extra-time and two more sealed it despite a late Reading goal.

Granted it may not have been an overturn to the extent of Barca’s but just as memorable for Whites fans.

Naturally, being on the wrong end is as deflating for the losers as it is joyous for the victors and one can only imagine how low that PSG dressing room at Camp Nou was the other night.

But no neutral really cares about those losers on nights like Wednesday, just like not many onlookers spared a thought for the Atlanta Falcons when they surrendered their 21-3 half-time lead last month to lose 34-28 to the New England Patriots.

Nor was there consoling words for the US team when Europe overhauled a 10-6 deficit on the final day to win the Ryder Cup outright in 2012 in what is now known as the miracle of Medinah.

Like underdogs winning in the FA Cup, we always want the impossible made possible and sport provides that excitement. Even as non-Barca fans watching on in midweek, it was hard not to get caught up in the moment.

The only downside was that many of us had to wait until the highlights to enjoy the action due to BT Sport’s domination of live coverage via subscription.

I suppose you get what you pay for and those of us who begrudge it will have to get used to it after the channel secured an extension to its UEFA rights this week.

If only ITV could muster a Barca-style comeback and get those rights back on Freeview.
