Newcastle boss Hughton delighted Campbell gamble paying off
The 36-year-old former England international has been used sparingly during his time on Tyneside so far after a late start to pre-season training.
"There are not too many frills about Sol, he just does the job efficiently and in the manner in which he is used to doing it, so I have never had any fears about him."
Hughton added: "He's an experienced player and he is vocal enough.
"You can gain that respect by what you say and by your presence, and the players are aware what a fabulous player he has been and is, so he has been a good influence."
