When looking at current Manchester United’s plight, fans are nostalgically looking at sir Alex Ferguson and his generations of players who won the Premier League with ease in the nineties and at the beginning of 21 century. But, even in those times, many problems happened behind the scenes at Old Trafford. In modern times, a lot of autobiographies and podcasts with former players appeared in public, along with their stories from the dressing room, and they revealed all scuffles and troubles which happened in ‘better times’.Keane stormed over to his player’s house: ‘Let me in’!Fans could hear about the famous Roy Keane and sir Alex Ferguson bust-up, Roy Keane and Peter Schmeichel fight, and now we have another Roy Keane incident, this time with his fellow teammate Teddy Sheringham. The London-born striker arrived to Manchester United from Tottenham in 1997 and it took him one year to feel Keane’s rage.Do you want an ice cream Patrick?As reported by the Times, Sheringham in a book published next week called ‘1999: Manchester United, the Treble and All That’, recalls a remarkable exchange during a bus journey from a night out with teammates in 1998.“All of a sudden, Keany said, “Why don’t you f*** off back to London in your f***ing red Ferrari and your penthouse?”‘ ‘I went “Eh?” And he says, “Yeah, f*** off back to London”. I’m like, “Are you coming for me, Keany? Why are you coming for me, you Paddy? F***ing what?” And he went “f*** off”, and he goes on “f***ing red Ferrari, penthouse…”. Then he jumped round, still with his bad leg, got me by the tie, pulled me towards him, grappling with him. Suddenly everyone’s going “what’s going on?” and pulling us apart” recalls Sheringham.’I motivated Fergie by telling him he will never be like Keane’Their teammates managed to pull them apart, but the striker thought that this conflict will follow the next day. Teddy admitted he had a sleepless night, thinking about what can happen the very next day.“I’ve seen Roy in the gym so I know it can go off. So I go in thinking, “Get yourself ready”. I actually go in to change thinking, “I’m ready for him”. You have your own cubicle so I was either next to Keany, or maybe the one after, and as I walked in, he’s there doing his shoes up. I walked in past him and I’m thinking he’s going to get up and boot me in the face. I’m thinking “here we go”. Keany gets up and walks out. He didn’t say a word to me. He didn’t say a word to me for the next three-and-a-half years” wrote Sheringham.Referee’s nightmaresEven with this incident, former Manchester and Tottenham striker revealed in TalkSport three years ago that Roy Keane and Paul Gascoigne are the two best players he ever played with. The pair continued to play together without talking and won the treble in 1999 and two more Premier League titles before Sheringham went back to Tottenham in 2001. He made 104 appearances and scored 31 goals for the Red Devils. Unlike Teddy, Keane didn’t speak much about the incident, but revealed it in his autobiography in 2002:“Teddy arrived for training on his first day at the club in his red Ferrari, every inch the confident Londoner. The chemistry between us was never right”.
