Portsmouth boss Tony Adams has warned fullback Glen Johnson not to settle on his current form.

"He's still a young man, he's still learning his trade," Adams said in the Daily Mirror. "The more I work with him on the training pitch, the better I think he's going to become.

"The best form of defence is going forward isn't it, and he is strong going forward, but if he wants to play for his country on a regular basis, he's got to do both sides."
