Former Manchester United captain Roy Keane has urged players from both sides to not go 'soft' in Sunday's derby between the Red Devils and Manchester City at Old Trafford.
Keane feels that present day players are starting to get a bit precious so has implored them to get stuck in on the weekend.
"Players are changing, they are having a fit when they get brought off or not brought on and a lot of them are going soft," he said.
"There's a skill in tackling and nailing people. Yellow cards are fine, you need to worry about the red ones. You can still leave your mark on a player but when I see United games now, even against Arsenal, everyone's being nice to one another. Everyone's gone a bit soft.
"I don't think it will be a cagey affair.
"United will be hurting from the semi-final and they will want to keep City in their place. If City won on Sunday that would shock everyone and that's why they need to be kept in their place.
"I think the progress City have made, if I was still playing for United City would be the game I would want to win more than anything else. They're serious challengers for the league."
