Sean Dyche felt new signing Chris Baird slotted in seamlessly into the side at Charlton.
The 32-year-old Northern Ireland international agreed a deal until the end of the season on Thursday.
And Baird was handed his debut at The Valley, in the absence of the injured Keiran Trippier.
Dyche was delighted with a player he played alongside at Watford a decade ago: “He’s played at the highest level.
“His fitness will improve, his sharpness will improve. He’s just a clever player.
“I played with him as a young man and he’s a very intelligent player.
“His game intelligence is where it’s at.
“You don’t play at that level and in a number of positions for that long.
“Fitness you have to work at, but game intelligence is always there.
“He’s kind of unflappable and that’s what those big players have got. He’s mode and secure and solid, good positioning, tough as you like, and delivered a very balanced performance.
“He was a young man when I played with him at Watford, but terrific then.
“You could smell it on him that he was going to go a long way. He’s had a very good career and he wants to continue that with us at the minute.”
Meanwhile, Sam Vokes hit his 20th goal of the season at Charlton - and Burnley now, with 25-goal Danny Ings, have two 20-plus goal strikers for the first time since Willie Irvine and Andy Lochhead in 1965/66.
Dyche said: “It’s a nice marker. I still feel there’s more to come from him and to be fair to him he’s grown within it.
“I’ve never understood numbers and limits.
“I told him to keep an open mind and he showed it again with a nice calm finish, and good play actually to get the penalty.”
