IAN Holloway believes that Angel Martinez can establish himself as an important part of Millwall's midfield after making his first appearance for the club.
Martinez made his Lions debut in the 1-0 win over Brighton last Friday.
The Spaniard suffered a calf injury just days after joining the club in September and has only recently been available for selection.
"I was delighted for Angel," said Holloway.
"That's the first time everybody has had the chance to see him and he gave us a balance in midfield, which we've been missing since we lost Nicky Bailey.
"If I'm being totally honest, Ed Upson and Scott McDonald should really be fighting for one attacking place. and with Angel and Shaun Williams in there, we looked a bit more solid.
"A bloke who's played 100 games in La Liga isn't going to be bothered by the pressure of our crowd or how it feels to be down the bottom of the table.
"We haven't had the chance to see him yet. Unfortunately, a 13cm tear in your calf, in the second week you're here, isn't really your fault.
"That was just the way it was with Angel so we've had a bit of bad luck, but he's caught up now and can be a really good player for us."
Speaking to the club's official website, Martinez added that he hopes to improve on his first Millwall performance.
"As a football player I feel useful again," he said.
"I came here really excited to play as soon as possible so to get an injury was so sad for me and my family.
"It was so difficult, but in your mind you have to stay calm and keep working hard all the time.
"Playing against Brighton is just the first step for me. It was the first time I have played with people like Scott McDonald and Willo (Shaun Williams).
"I didn't have the chance for pre-season games so I need the chance for some adaptation to get more confidence.
"It is not easy to play your first game in December and I am going to have to improve and grow.
"Personally it wasn't my best game, but I think I will adapt more and get better every day. I just felt really happy that I could help the team to win."
