Roy Keane offered a blunt response after spotting a quick embrace between former team-mates Jack Grealish and Ross Barkley on Tuesday evening. <br /><br />The former Aston Villa stars were both in action as Grealish's Man City stormed to a 6-2 victory over Luton Town and booked their place in the FA Cup quarter-finals.<br /><br />Despite the convincing win for City, it was a disappointing night for Grealish, who had to be consoled by teammates after being forced off in the first half due to a fresh injury setback.<br /><br />Grealish was seen hugging his former team-mate Barkley, who started the match in midfield for the Hatters, before kick-off at Kenilworth Road.<br /><br />ITV host Laura Woods pointed out: 'Ross Barkley and Jack Grealish having a little cuddle before the game.'<br /><br />Roy Keane, who was also on punditry duty on Tuesday night, quickly chimed in and said: 'Not for me. But we're all different.'<br /><br />Back in 2020-21, Grealish and Barkley played one season together at Aston Villa after Barkley joined the club on loan from league rivals Chelsea.<br /><br />The two players avoided punishment despite breaking coronavirus restrictions to attend a party in London during their time together.<br /><br />Grealish was unable to make an impact on the FA Cup tie at Luton, with Erling Haaland stealing the headlines after scoring five of the goals.<br /><br />City playmaker Kevin De Bruyne also stepped up after Grealish picked up an injury as he provided four assists at Kenilworth Road.<br /><br />The 28-year-old winger was forced off before half-time in City's thumping win and was visibly distraught by his latest injury. <br /><br />The England international was replaced by Jeremy Doku after 38 minutes with Pep Guardiola.<br /><br />After coming off, an emotional Grealish was seen hiding under a training jacket before his teammates consoled him.<br /><br />'Looks like it [a recurrence of the groin injury],' Guardiola said after the game. 'It's the second time. Hopefully this time he can recover well.'<br /><br />'I didn't speak to the doctor but I think he was complaining a bit about his groin. He felt really good but unfortunately was injured again. It's been a tough season for him. He'll have to recover well and help us when he's able to come back.'<br /><br />The injury came after Grealish quickly recovered from a groin problem sustained in Copenhagen a fortnight ago to start against Luton on Tuesday night.<br /><br />While Grealish cut a distraught figure on the touchline, the England star still took time to congratulate his team-mates on social media, along with a message on his injury.<br /><br />Grealish wrote: ' Well done boys, ' underneath a re-post of City's full-time FA Cup graphic. Away support was unreal!!! Hoping my injury isn't too bad with two praying emojis following it. <br />
