Southgate backs Man City's Johnson for World Cup spot
Southgate was in charge of the 22-year old Manchester City man during his tenure at the Riverside Stadium and believes his style of play will be valuable to Capello.
"Adam can beat people from a standing start and can dribble between people, which could make the difference in a tight international game," Southgate said.
"He has also finished the season strongly with Manchester City.
"I would take him if I was manager, along with Joe Cole. They might be wild cards but you could throw them into a game to open it up.
"At the moment it doesn't look like Shaun Wright-Phillips will go. He didn't have any involvement the other night.
"Adam is pretty confident in his own ability and his world has changed a lot in the last six months."
