Steve Agnew says Boro are prepared to do the hard yards to topple league leaders Chelsea at Stamford Bridge on Monday evening.
It's a game with plenty at stake - the Londoners will be looking to extend their lead at the top of the Premier League, while Boro are fighting for survival at the foot of the table.
Agnew says the Teessiders have shown what they are capable of in last weekend's 2-2 draw with Manchester City.
"It was a terrific game to be involved in," he said.
"We showed a fantastic fighting spirit to twice take the lead and I thought we had enough to see it through.
"I think what we do is take confidence and belief forward."
Agnew singled out Alvaro Negredo following the Spanish forward's goal and assist against his former club at the Riverside.
"Alvaro's been a pleasure to work with," he said.
"He's a top striker and has all the qualities to put the ball in the back of the net
"I think we've provided him with more opportunities, but he's stayed connected with the team when we've been defending spells in the game.
"We've shown different ways and ideas of how to become more of a threat, and he's been a massive part of some really good performances in recent weeks."
The Head Coach says Boro are under no illusions as to the size task at hand as they head for the capital on Monday.
"Chelsea are a top team, full of top players with a wonderful coach," he said.
"Offensively they have so many creative options and can play with such speed, but at the other end they are incredibly well-organised.
"It's a very difficult fixture, but we've taken a long look at them and we'll be ready for the game."
Agnew says Sam Allardyce's Crystal Palace have provided a template for the desire and determination that is required, following the Eagles' 2-1 win over Chelsea at the beginning of April.
"Any team that beat Chelsea are going to have to work extremely hard," he said.
"We can talk about tactics and formations, but the bottom line is that they put in a hell of a shift.
"That's what we'll aim to do as well.
"The position Chelsea are in, I don't think they will be complacent - they'll be committed as always. But what I will say is that they will get a proper game of football."
