Erm. Need to take Rashford? No, they don’t. The author already suggest three barriers to any potential playing time in Vardy, Kane and Sturridge. I don’t know why he dismissed Welbeck from that category when he’s been decent enough since his return from injury and he’s more experienced than anyone not named Rooney or Walcott as far as attacking options go. Yes, Welbeck can play wide and might just do that but he would still be ahead of Rashford centrally.
So, no. England doesn’t need to take another “Oh this guy played well and has potential” player. Another full season with Manchester United then he can work his way into the 2020 World Cup plans.
