Millwall boss Neil Harris says Fred Onyedinma’s injury won’t affect the club’s transfer plans in January – and insists signing an attacking player is still the priority.

Onyedinma, one of four Lions strikers, is expected to miss most of December with a groin problem.

It leaves Harris having to choose from Steve Morison, Tom Elliott and Lee Gregory for a front two partnership.

He said: “We’re looking to bring in another attacking threat to the club - that won’t change.

“Barring the first week of the season, we’ve had Tom Elliott injured, Steve Morison injured, Lee Gregory suspended, Aiden O’Brien suspended, Jed Wallace suspended and now Fred’s injured.

“We’ve not had three senior substitutes available in attacking positions. That’s because we’ve got a tight squad.

“There’s no point me saying we’ve been short of players – the reality is we have been – and we’ve got a chance in January, financing dictating, to bring a player in.

“Fred being out injured has highlighted the fact that we’re one attacking threat short, changes wise. We’re certainly looking to address that as soon as we can in January.

“No one is going out the door unless we feel it’s necessary for their development. It’s about adding to what we’ve got and making sure we’ve got enough players.

“We need all the players involved, fighting and pushing for places. You’ve seen with Tony [Craig] coming in and doing so well against Burton and Mahlon [Romeo] against Sheffield United.

“Ben [Thompson] has come on in the last couple home games and has been outstanding. He looked really fresh and hungry. So we’ve seen that everyone’s going to be needed.”

Millwall academy graduates Kris Twardek, Harry Donovan and Chris Mbulu have been in matchday squads this season.

And while Harris is pleased with their progression, he wants to have more options from the bench.

He added: “They’ve all got potential at this football club, but realistically, they probably need to play some football at Conference or League Two level before playing for us.

“It’s a big ask for them to be involved [with the first-team], train at the tempo, intensity and quality that we have every day.

“It’s a great learning curve for them, but we need more options.”
