Head coach Aitor Karanka says his Middlesbrough squad have a hunger and a "want" to keep up their bid to reach the Premier League this season.
Boro are among the contenders for promotion from the Championship having accumulated 39 points from 21 games, and are joint-top with Bournemouth.
The Teessiders are unbeaten in eight games, winning each of their last two.
"The spirit we have in the team is the main thing for me, the players always want more," Karanka told BBC Tees.
"We have to fight for more and we want more. It's good for us, when you look at the table and our position now is to be proud of.
"It's not a coincidence, we're working to achieve this position but we have to keep working in the same way and forget the past, the future is the main thing."
January provides Karanka with an opportunity to add to the squad following the opening of the transfer window, although his interest in others players may depend on the availability of those currently returning from injury.
One such player is Rhys Williams, a versatile Australia international who has been absent since the start of the year with an Achilles injury and whom finally returned to match action with the under-21 side in midweek.
"It's good, it's important for him to have those feelings after the game," added Karanka.
"But he has to keep calm, because he has been out for 10 or 11 months and it's difficult to get fit again.
"Now he's an intelligent and experienced player who has done well in the training session but needs to be calm."
