SPHINX boss Luke Hopkins tore into his side after they crashed out of the FA Vase Trophy and he also questioned their passion to play for the club.
A 3-2 home defeat to Studley at Sphinx Drive has proven to be the final straw for Hopkins who was left angered by another cup exit.
After falling behind to a Matthew Bailey goal, Nic Evangelinos and Christopher Gumery handed the hosts the initiative in the second period.
But a second from Bailey and a Jarrell Hylton goal five minutes from time put the Midland League Division One side through at the expense of Sphinx.
Hopkins apologies for those who paid to watch the performance on Saturday and threatened to make drastic changes.
He said: “I pick the team that I think can win games of football and when they go over the white line I expect every player to give their all and work for each other and the shirt they are wearing.
“This hasn’t been happening for the last five or six games and there seems to be an attitude developing that the players are their station.
“I think it’s time for a big change and this week there will be a large amount who are unhappy and are free to find other clubs because no matter what your ability level is if you have no work rate and will to win you are no good to me.
“I think a lot of the players need to take a long look at themselves and realise how much people do behind the scenes to allow them to turn up hassle free on a Saturday and play football.”
As for the match itself, Hopkins believes Sphinx should have showed more desire to progress in the competition.
He added: “The game was there to be won and again we were in the driving seat at 2-1 up.
“Studley weren’t a bad team, but no disrespect to them they weren’t brilliant. They just wanted it more and were prepared to work hard for a result.
“It’s the FA Vase, the best chance any of these players will have of playing at Wembley and winning a trophy.
“They shouldn’t need to be got up for games like that, but perhaps that’s the mentality of players nowadays.”
Hopkins’ side will have a chance to bounce back when they host Loughborough University this Saturday.
*Alvis Sporting produced their best performance of the season to defeat league leaders Littleton 2-1.
Two late goals from Michael Healy earned Alvis all three points and a win which moves them up to 14th in the table.
Coventry Copsewood drew 2-2 at Stafford Town and are now placed seventh.
Both sides meet each other this weekend in the cup.
