Lockyer returned to football after a two-year absence with Bristol Rovers in October under Clarke, who he played for at the club at the start of his career.
He said it had been a “tough couple of months for everybody” at the club as they slid down the table, and that the mood in the changing room after their win was not “too jubilant”.
“We know our standards haven’t been anywhere near good enough this last calendar year,” Lockyer said.
Rovers have picked up four points (W1, D1, L2) across Evans’ first four matches in charge and Lockyer said you could see a “reaction” from the players to his appointment.
While they lost 3-2 to league leaders Bromley, they led for 54 minutes until Shaq Forde was sent off, and against Barnet, they were undone by two goals from set-pieces.
“The gaffer’s come in now and he’s demanded a few non-negotiables, which I like, which I can get behind and can bring success and you’ve seen a reaction of sorts,” Lockyer said.
“To come away to Shrewsbury, defend set-pieces and be big, strong and ugly and do the dirty side, but the basics I’d call it – obviously Fab [Cavegn] has put them away really well as well – I thought we fully deserved the three points.”
