"I feel a little bit for Rashford. If Rashford was in Manchester City's team, he would get 30, 40 goals a season," Richards told Sky Sports after City's Carabao Cup semifinal win at United last night.
"Obviously on the counter-attack when you've got Martial, Lingard, James, they look good.
"Sometimes, the counter-attack isn't on. You've got to be able to pick through teams. You look at City's midfield compared to United's and that's no disrespect to them. De Bruyne first thought is 'let's play a forward pass'.
"When I see United play, it's all just a little bit too safe. 'I don't want to be the one to make a mistake today so I'll just play a simple pass'. You look at City's midfield, first option 'let's play forward'."
