Alex Pearce claims he was excited to join Millwall since hearing of the club's interest, and is eager to get down to business after completing a loan deal from Derby County for the rest of the 2018/19 season.
The Republic of Ireland defender - who has a wealth of Championship experience as well as competing in the Premier League - completed his move to The Lions on Friday, and has spoken of his delight at the deal.
"I'm really pleased to be here," Pearce says.
"As soon as I heard about the interest from Millwall, I was excited about coming here and hopefully I can help the team climb up the League."
The 30-year-old explains that manager Neil Harris was a key reason for his decision to move south, commending the boss' enthusiasm.
"The manager's enthusiasm was key. I met with him, we had a good chat, and we spent a good amount of time together.
"He was really positive - he told me about how he likes his teams to play, and I was really enthused by it all. Everything went really positively.
"I'll always give 110% every time I'm asked to play. I'm predominantly a centre-back, I'll be strong in the air and try and play when we can, though obviously we do like to operate with a direct style of play - which hopefully I can fit right into."
Pearce spent much of his senior career with Reading, lifting the Championship title in 2012, and is consequently familiar with several of his new teammates at The Den.
"I know Jem [Karacan] and Coops [Jake Cooper] from my Reading days, and some of the other boys from when we've played against one another.
"It's always good coming into a new dressing room when you know a couple of the lads beforehand."
Subject to FA clearance, Pearce could be in line to make his Millwall debut this Sunday as The Lions take on Hull City in the Emirates FA Cup.
"I'm hoping to be involved on Sunday, of course. It's a good game to come into, a tough one against a good Hull side, but hopefully one in which we can progress to the next round."
