Five moments of madness from birthday boy Roy Keane

Former Manchester United and Republic of Ireland captain Roy Keane is celebrating his 44th birthday today, having retired from football back in 2006 following a final season with Scottish giants Celtic.

Whether the Cork-born former Old Trafford hero will be enjoying wild celebrations remains to be seen, but during his Premier League days, Keane produced many moments of madness on the pitch which kept us all entertained.

Here are five of those moments for you to relive on the fiery Irishman’s latest landmark.

Soccer - FA Barclaycard Premiership - Manchester United v Arsenal

Southgate stamp 1995
During an FA Cup semi-final replay between the Red Devils and Crystal Palace, United’s fearless leader aggressively stuck the boot in an incoming Gareth Southgate, who had made a lunging tackle.

Later, after Keane had retired, he stated that this incident was one of very few he actually regretted during his playing time, though also maintained it was actually Southgate’s fault.

The pair have mended bridges now, having done coaching badges together and regularly work as pundits for club and international matches on TV.

No doubt Louis van Gaal would love a character like Keane in his current set-up, with the Red Devils 5/1 to win the title this season with Coral.

Watch that vicious incident occur between Keane and Southgate at Selhurst Park a decade ago.

Shearer spat 2001
Known for his never-say-die attitude on the pitch, Keane embodied the fighting Irish spirit, but overstepped the mark on many occasions, including against Newcastle United in a league encounter.

The former midfield enforcer was heading for defeat against the Toon and decided he wanted a piece of Alan Shearer, throwing the ball at the Magpies number nine, before lashing out and receiving a red card for his attempted right hook.

See the clash here, as Keane is sent off, and not for the first time in his United career.

Ending Haland’s career 2001
Now an infamous moment in the Premier League, Keane brutally crunched Manchester City’s Alf-Inge Haaland with an incredibly high tackle, ultimately ending the defender’s career.

In what Keane declared was an act of revenge for Haaland claiming the Irishman was playacting in 1997, having picked up a serious cruciate ligament injury when the pair collided, the former United skipper later said he never regretted his actions.

Watch that horrific tackle again right here and see how Haaland’s career was brought to an abrupt end.

Tunnel tussle 2005
When Keane is mentioned, Patrick Vieira’s name isn’t usually far from the lips, with the feisty duo having endured an intense rivalry when United and Arsenal were tussling over domestic dominance.

In a now famous top-flight moment, Keane verbally lashed out at the Frenchman in the tunnel before the game between these two clubs had even started, adding even more fuel to this already heated clash.

Ipswich interview 2009
After his retirement in 2006, Keane never mellowed, eventually entering a managerial career with Sunderland and Ipswich Town, while he now is enjoying a coaching role with his country, who are 13/5 to qualify for Euro 2016.

In a 2009 press conference with Ipswich, the media were met with fury, as Keane refused to admit Ireland’s misfortune after Thierry Henry’s scandalous handball, before angrily singling out a reporter whose phone goes off at an untimely moment.

Watch and squirm here as Keane lays into the reporters during his time with Ipswich.
