Millwall defender Danny Shittu still believes he is of Premier League standard despite signing a three-month deal with the Championship outfit.
The former Bolton player, who left the Trotters by mutual consent in the summer, penned a short-term deal with the Lions earlier this month.
Nigerian international Shittu, who played in the World Cup, has not ruled out extending his stay at The Den but is adamant he is worthy of top level football.
"I know no Millwall fan will be upset for me to say I know I'm a Premier League player," Shittu told The Sun.
"I've played in the World Cup, I've played against top quality players. If you ask Premier League strikers who they fear the most, they would mention me.
"I know I'm one of the best defenders. I've got a lot to prove and I've got many years to go - I'm fit, fast and dominant.
"I know there will be people coming to watch but that's not the main thing - I'm here to play for Millwall and give 100 per cent."
He added: "It would be great to stay longer but initially it's just a three-month contract and we'll wait and see what happens in the future."
Shittu made his debut in the Lions' win over Derby last weekend and he is hoping to add goals to his game during his time at Kenny Jackett's side.
"I'm a defender but I like to go forward and score goals," said Shittu, who once scored nine goals in a season during his time at Watford.
