KENNY Jackett vowed to keep a lid on any talk of promotion within his squad after Millwall broke into the play-offs with a 2-0 win at Blackburn Rovers.
Stunning goals from Chris Wood and James Henry at Ewood Park moved the Lions into the top-six for the first time this season – and to the top of the Championship form table.
Millwall have now won four of their last five matches and can extend their unbeaten run to 12 when they face Wolves on Tuesday, which would be their best-ever streak during Jackett's five-year reign.
But the Lions boss says he will be keeping his players' feet on the ground. He said: "These are heady days, but we'd be foolish to start talking about the Premier League with a game coming up.
"There's a terrific work ethic and spirit within the group and we want to keep that. We've got to keep believing in ourselves.
"But we have to stay level-headed. I hope that this type of victory, as when we went to Nottingham Forest a few weeks ago, gives the players confidence but not over-confidence.
"Results like this should show them what they can achieve when they work hard and apply themselves. The games come very quickly and we can't dwell too much."
Having been relegated from the top-flight last season, Wolves find themselves without a win in their last nine games and were beaten 2-1 by Forest at home on Saturday.
But Jackett is wary that his side could face a backlash in the Midlands and says his players cannot afford to take anything for granted.
"We go to Wolves next and they're another big club like Blackburn – you have to do everything right to get results at places like this," he said.
"We then come back to The Den for a local derby against Charlton so it's a big eight days for us. I don't want the players to sit back or rest on their laurels.
"Credit to the players because they've applied themselves and we have a good balance within the team. We should be confident while we're on this run as long as we're not complacent.
"As the results showed on Saturday, this is a very competitive league and you get surprise results all the time. We have to identify what got us the points at Blackburn and focus.
"It's a fantastic run in a very competitive division. In the second-half at Blackburn we had to dig in more than at any other time, because they have a lot of quality.
"I'm very pleased and very proud of the run. But unless we apply ourselves, it won't get us anything at Molineux."
