Ex-Manchester United skipper Roy Keane would have given Alejandro Garnacho a stern lesson on the training ground for his recent display of petulance, according to one former star.
Garnacho, who has fallen out of favour at United, stirred controversy by posting a picture of himself donning an Aston Villa shirt with Marcus Rashford's name and number on social media.
Rashford was loaned to Villa for the latter half of last season following a falling out with manager Ruben Amorim, and Garnacho's audacious move was perceived as a jibe at the United boss, having experienced a similar fallout with him.
Garnacho was left out of the squad for United's 1-0 Europa League final loss to Tottenham in Bilbao, which led the winger, who celebrated his 21st birthday two days ago, to publicly criticise Amorim and hint he was contemplating his future.
This reaction from Garnacho convinced Amorim that the player does not fit into his future plans, with the Red Devils now actively seeking to offload the £50million-rated Argentine this summer.
Former United forward Louis Saha suggested that Keane, known for his no-nonsense approach, would have dealt with Garnacho's antics by subjecting him to a series of tough tackles during training to put him in his place.
"Back in my day, I think Roy would have welcomed Garnacho back to the training ground with a few crunching tackles to help him understand what he thought of him," Saha remarked. "I can't say for sure, but I really doubt Keane will agree with what Garnacho did.
"It's the type of things we see from new generations. To be honest, I can't only blame Garnacho. The way the squad has been built, it's why Garnacho thinks he has the right to do something like this.
"It's why he thinks he can make stupid comments and say things on social media. He thinks he's going to get something out of it and, right now, United are the club who are giving him the platform to act this way.
"He already thinks he's a top player, already makes demands, acts without respect. It's a shame, but there are other factors than just the player. The club and the squad, they've already lost the leaders. The bad influences have already taken over. They think they're bigger and better than they are.
"Keane, Rio Ferdinand, David Beckham, Gary Neville, they would all make sure you understand what wasn't allowed. They wouldn't give players the luxury to act like this. He's been let down because he's been given too much responsibility for a player who hasn't earned it yet.
"It's fine if you're playing like Wayne Rooney. If you score 20 or 30 goals a season, do what you want, demand what you want. Garnacho has five goals and he's carrying on like this. It's crazy."
When asked about a potential swap deal involving Garnacho and Chelsea striker Christopher Nkunku, Saha responded: "Everyone can benefit from the move. It's a win-win. United want players who are dedicated, work hard, are eager to play and who have talent.
"We want players who want to play well, and there's extra motivation in the year of a World Cup. I think Nkunku knows if he plays well, he can get back in the French squad for the summer. At the same time, he's not the kind of player who disrupts the dressing room.
"As for Garnacho, if he wants to go, get rid of him. I used to be a huge fan, but that's over. Anyone like this, if they want to go, go. Even if you lose money, it doesn't matter, because you can bring in a player who can behave as they should."
