Walker has brought in Greaves as York skipper and the former Hull City man endeared himself last week, revealing he was here to help and not to call the orders.

Greaves led York to an opening day win at Crawley Town but that was nothing compared to Thursday evening when the 33-year-old scored the winner against title favourites Wrexham led by his former manager at Hull, Brian Little.

Walker will take a matchwinner any day, but admits Greaves' hands-on approach to help and mentor the club's younger players is a breath of fresh air at KitKat Crescent.

"He's a big man in lots of ways as he commands not just the pitch but the dressing room as well," said Walker.

"All the players respond to him and one of the main reasons I brought him in was that so many people spoke highly of him – people who have worked with him over the years.

"He probably thought he was coming here just to be a centre-half, but he does so much more than that and he is invaluable.

"He's very good and the other thing he has helped with is bringing on Simon Rusk as he played with him at Boston. He has been there to help him.

"He is a good captain, he is helping with a lot of responsibilities and he takes some of the pressure off the manager and the coaches."

York have began with a huge bang even though Walker looked to have a developing 'keeper crisis on Thursday when loanee shot-stopper from Birmingham City, Artur Krysiak, dislocated a finger in the Setanta televised clash with Wrexham.

With summer signing Michael Ingham still injured, 19-year-old rookie Josh Mimms was thrown into the limelight but, from there, Walker's problems eased a little.

Mimms, son of stalwart goalkeeper Bobby, had an absolute blinder and with Krysiak going back to his parent club and Ingham still injured, the teenager was odds on favourite to start yesterday's hosting of Histon in the Blue Square Premier.

Ingham is now less than one week off a return but the York manager revealed City's new whizz-kid has given him a headache as to who to start in goal.

"It was my decision to bring somebody else in and I explained to him my reasons," said Walker.

"He was not happy with that, but he took it really well and, as is usually the case in football, without anyone seeing it he then gets his chance and I thought what he did was fantastic.

"Krysiak has now gone back to Birmingham and that is disappointing, but Michael Ingham is back in seven days so I have no problems there.

"He is trying to play part of the reserve game on Tuesday.

"It's up to Josh now.
