The 26-year-old has been a key figure in the Saddlers defence when fit since joining from Blues two-and-a-half years ago.
That time has seen him develop in some crucial years for his career and when asked if he is eager to continue to learn, he said: “Yeah definitely.
“You can always keep learning. You always want to progress in your career and you take pride in it.
“I always want to do the best I can.”
Scarr has been partnered with either James Clarke, aged 31, or Mat Sadler, aged 36, in the Walsall defence and he insists both have been integral in improving his game.
“They both bring different qualities and I’ve been able to pick up different things,” Scarr added.
“Playing next to someone, without realising you imitate what they do and pick up little things. It’s been a massive help for me. Me and Sads go through clips after games. I always text him after a game and ask ‘what could we have done here’ or ‘what could we have done as a team’.
“It’s been a massive help.”
