Boro travel to Anfield on Tuesday night for their third round Capital One Cup tie against Liverpool, and Head Coach Aitor Karanka has stressed to his team that they must remain calm going into the fixture.

"I think everyone is excited to go to Anfield, but we have to keep calm because I know how difficult it's going to be," said Aitor. 

"We're going to play against one of the better teams in the Premier League as a Championship team, so we have to go there and give 100%.

"It's a great place to go and play football - one of the best, but we have to think that we are going there to play football and we are going to play against a very good team. 

"If we go there to enjoy it we will have problems, so we have to be ready for a very hard game."

Liverpool go into Tuesday's game on the back of a disappointing loss to West Ham, whereas Boro are enjoying a spell of good form following three straight wins in the Championship. 

This difference in recent form between the two sides has sparked comments that it could be an ideal time for Boro to face the Reds.

However, Karanka said there is never a good time to play a team with the stature of Liverpool. 

"All of the players who are going to play on Tuesday will be from my first squad," said Aitor.

"After beating Brentford, I know we can change the squad and win so I'm very happy knowing we can play well.

"You never know when the best time to play a team is. I know the Spanish league very well - look at where Real Madrid were last week and where they are now scoring eight goals in a game. 

"It's the same with a team like Liverpool - there is never a good time to play them."

Boro will be backed by an away support just short of 3,000 after selling out the ticket allocation, and Karanka said he is delighted that the fans have the opportunity to watch the team at Anfield. 

"The best thing for me is that our crowd can enjoy a game against Liverpool," said Aitor. 

"It's the most important thing that they will remember the time they went to watch Middlesbrough play at Anfield."
