Cahill, who played inside Jones at centre-half, said: "I thought Phil did really well, he got forward when he could, he defended well in really difficult circumstances.
"It was a hard game for him to get his first cap. It was a big game and conditions didn't help him.
"But he has already looked at home with Manchester United this season since moving there.
"He did really well in Montenegro. He really stood up to the task and seeing youngsters coming through and doing well is great for England.
"I think we are in really good shape. We've got young players coming through now with a blend of experience as well.
"That will stand us in good stead for the tournament and a couple more games before we get there. I think we will do really well."
