NEIL Harris insists his caretaker role at Millwall will not become permanent.
Harris and academy boss Scott Fitzgerald have been placed in temporary charge of the Lions in the wake of Steve Lomas' departure.
The duo took training for the first time on Friday ahead of Sunday's trip to Doncaster.
Harris, speaking to the club's official site, said: "I was sad for myself and the staff that Steve's gone. He brought me back into the club and I enjoyed working with him.
"However results drive this business and ours haven't been good enough.
"I have spoken to the chairman and some of the board and Fitz and myself have been asked to take this on game by game, starting at Doncaster until the new manager is appointed.
"In the short term I am concentrating only on getting a team out there capable of getting a result at Doncaster.
"Longer term, I'm looking forward to continuing as U21s coach and helping out with the seniors as required.
"We have got a few little ideas which we'll try to put across to help the boys. We have to prioritise cutting down on the goals we're conceding particularly from set pieces.
"There are players here with good pedigree who are capable of doing better than they have so far, and it's up to us to get the best out of them.
"We are looking for a performance which makes the fans proud."
