Jamie Carragher reminds Roy Keane of Ronaldo comments after Man United defeat

'Roy Keane told me Man Utd had signed Ronaldo to win the FA Cup'

Jamie Carragher gave Roy Keane a brutal reminder of the comments he made about the reason why Manchester United signed Cristiano Ronaldo. United were dumped out of the FA Cup in the fourth round on Friday night after losing on penalties to Championship side Middlesbrough. Ralf Rangnick's side had chances to win the game in the 90 minutes but squandered plenty of chances including Ronaldo himself, who missed a penalty in the first-half. The defeat has sparked yet another inquest into the problems at Old Trafford as a chance to win silverware went begging yet again   - with Ronaldo's frustrations evident at full-time. After the 36-year-old made his return to United, Keane and Carragher were locked in debate over the club's decision to re-sign the forward with the former Ireland international claiming United had signed him to win trophies such as the FA Cup. Following their embarrassing defeat on Friday, Carragher instantly used the opportunity to remind Keane of his comments on Twitter - just in case the pundit had forgotten. He tweeted: "Roy Keane told me Man Utd had signed Ronaldo to win the FA Cup." https://twitter.com/Carra23/status/1489734346479124486?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1489734346479124486%7Ctwgr%5E%7Ctwcon%5Es1_&ref_url=https%3A%2F%2Fwww.dailymail.co.uk%2Fsport%2Ffootball%2Farticle-10479491%2FJamie-Carragher-gives-BRUTAL-reminder-Roy-Keanes-comments-Cristiano-Ronaldo-FA-Cup.html The debate occurred back in November after Keane expressed his shock at the decision to substitute Ronaldo whilst Carragher questioned the reasons behind United's decision to sign the Portuguese international. Carragher said: "Why did Man United sign Cristiano Ronaldo? They signed him to stop him going to Man City. There was no plan to sign Cristiano Ronaldo." Keane fired back by saying: "He was always going to play, he wasn't coming back to Man United to stop him going to Man City but sit on the bench." The former Liverpool man then responded by saying: "Are United closer to the league title than they were last season? No. You speak about goalscorers, you bring your own input to the team, but it's a team game.' Keane hit back that Ronaldo was never brought back to United to win titles." Keane again hit back saying: "It's the FA Cup and getting in the Champions League. They've got to next round of the Champions League, how much is that worth to the club? If you're looking at the business side of it, that's why he's come back." Related links:
