STEVE Morison says he wants to help the club "get back where it should be" after signing permanently for Millwall for the second time.
The 31-year-old joined the Lions yesterday on an initial one-year deal after two years at Leeds United.
Morison was part of the last Millwall side to win promotion from League One in 2009/10, scoring in the play-off semi-final second leg against Huddersfield Town.
He partnered his new boss Neil Harris up front in the 1-0 win over Swindon Town in the final before leaving for Norwich City a year later.
The former Stevenage centre-forward told the club's official website: "I know what this place is all about. I know what Neil is all about, what the fans are all about.
"I'm not coming here under any illusions that this is going to be an easy ride. I'm playing for my future, the club needs to get back to where it should be and hopefully we've got everything in place to get us there."
Morison completed a full pre-season with Leeds and scored against Eintracht Frankfurt in a friendly in Austria two weeks ago.
He was still training with the Yorkshire club up to two days ago but is now getting ready for the trip to Shrewsbury this Saturday with his new team-mates.
Morison scored 20 league goals during 2009/10 and Harris believes being back at the club is motivation to aim towards a similar target again.
He said: "This is where he has played his best football and this is where he finds the fire in his belly to perform. He is desperate to start scoring goals for Millwall again."
