The midfielder has penned a one-year deal for his third season at the club – after the first two were both curtailed prematurely due to Covid-19.
Walker, 30, is a former team-mate of boss Gavin Cowan and a big part of the Bucks chief’s plans.
He was given captaincy duties last season, taking over from Shane Sutton, who left to join Newtown.
Former Nuneaton and Brackley man Walker insists he is at AFC Telford to be successful, stresses that OK is ‘not good enough’ and believes those ambitions align with the manager’s.
“I’ve known the gaffer for a long time, I know what he wants to do and that is be successful and that’s exactly why I came to the club,” said Walker, who is one of six existing players to commit for next season, alongside new recruit Kai Williams.
“It wasn’t just to do OK, OK is not good enough and that’s his opinion as well as mine.
“The unfinished business is that I do believe the squad we had – and continue with and hopefully increase with a different calibre of players – we can push on and get where we want to be.
“That’s challenging in this league. It’s a very, very tough league with a lot of full-time clubs but I truly believe we can have a good go at it this season and be where we want to be.”
Cowan has made no secret of his desire to have Telford battling at the right end of National League North, as they did in the manager’s first season, when they just fell short of the play-offs.
But the boss has stressed the difficulty of mixing it with the league’s well-financed big-hitters.
Walker, who has played 49 league games in two null and void season for the Bucks, added: “I’m really pleased to stay with the club, I’ve really enjoyed my time here and I want to kick on and finish what we started moving forward.
“We could’ve never predicted what’s happened to happen, so to speak, but these are the challenges you face and luckily the world’s coming out of it now and we look forward to welcoming the fans back.
“They were definitely a massive miss last season when they weren’t there, hopefully we can kick on in the new season with the fans behind us for a full season.”
Walker’s second season as a Buck was played out in front of empty seats for the majority of the shortened campaign.
