LOAN signing Jos Hooiveld will prove to be an important addition to Millwall's squad, according to boss Ian Holloway.
Hooiveld is in line to make his Lions debut against Reading tonight after moving to The Den from Southampton on a loan deal until the end of the season.
The Dutch defender was a key figure in the Saints side that finished second in the Championship in 2012 and went on to play in the top flight.
A left-sided centre back, Holloway hopes Hooiveld will bring much-needed balance, experience and stability to his back four.
Holloway said: "He's 31-years-old, got Southampton promoted and has played at a higher level. It's a fantastic opportunity for us to add someone like him.
"He's a leader, a good communicator and I'm delighted to have him."
Hooiveld took part in non-contact training with Millwall yesterday prior to the move going through and will be in the squad this evening.
It has been ten days since the Lions' last fixture – a 3-1 defeat to Ipswich – and Holloway has used the break to bed in his new signings.
Diego Fabbrini, Dan Harding, Shaun Cummings and Stefan Maierhofer all started against the Tractor Boys and will form the core of the team between now and the end of the season.
Reading were in FA Cup action at the weekend, beating Cardiff City 2-1 in South Wales.
Holloway added: "Reading played a different formation on Saturday so which shape is it going to be tonight?
"They've got Nathaniel Chalobah from Chelsea now so they've got another good option in midfield.
"The new signings showed some good things against Ipswich and we've done a bit more work with them since then.
"It wasn't ideal having to wait for a new signing to come in yesterday morning but that's the way it is during this transfer window.
"The spirit is the group is improving and everyone is looking forward to taking Reading on."
