Brentford – in 11th – are the only team outside the current top 10 that Wolves have played this season, with just one point gained at Nottingham Forest.
“It is not about the coach, it is not about anything but ourselves,” said Lemina. “After the international break we need to be honest again with ourselves and try to work things out and be committed to the plan, that’s it.
“We have just one point, it is really bad but I am really sure that we are going to come back from this. It is going to be tough after the international break, mentally, but we have to believe in ourselves.”
Wolves have more difficult matches after the international break, hosting champions Manchester City at Molineux before a trip to Amex Stadium to face Brighton.
Lemina added that City are not “superhuman”, before explaining: “There’s no excuses now. We have got to put our heads down and work really hard.
“The game is at home and I know we are going to have the support from the fans. We are going to try everything to win the game.”
