Worcester City boss John Barton has issued a "shape up or get out" ultimatum to some of his players.

Barton was so incensed by his side's poor display in Saturday's 1-0 defeat at Moor Green that he ordered the squad in for extra training yesterday morning.

The Worcester boss believes some players, although he declined to name names, are not pulling their weight and says if they don't want to play for the club, they should leave.

He said of yesterday's unscheduled training session: "I will let people draw their own conclusions from that action.

"It might have inconvenienced the players but it certainly inconvenienced me as well.

"Saturday's performance was shocking, the worst since I have been at the club.

"We have to start getting people who want to play for Worcester City, for me and for the St George's Lane spectators, and anyone who doesn't can go."

Barton may use the opportunity to bring in fresh faces but warned: "The idea sounds good and appealing but it is not as easy as that. It will be very difficult."

He believes their good results this season are masking deficiencies in the side.

"After the win at Halesowen we went to 32 points and that was in front of what I thought it would be at this stage.

"We have over-achieved to a degree at the Lane but the dangers have been seen. We have not been kidded by an improvement -- to be where we want to be, we still have some way to go.

"A little bit of application could have made the difference on Saturday. I couldn't fault them for that against Margate but it wasn't there against Moor Green.

"It was clear to see why Moor Green are doing so well. They are hard-working and their collective efforts produce good team performances. We have had a lot of those since I have been at the club but we need to turn these in our favour."

City have dropped to ninth place in the Dr Martens League Premier Division, but could climb back up to fifth if they can win tomorrow's game at Salisbury City.

Barton hopes his players will respond positively to Saturday's disappointment, adding: "The ball is in their court. If they haven't got the message now I don't think they ever will."
