Grant Leadbitter opened the scoring against Huddersfield after converting his penalty and Gaston Ramirez pounced on a loose ball before finishing to double the advantage before the break.





It would eventually finish 3-0 to Boro, but Kalas insists the team took nothing for granted in the dressing room at the break and says David Wagner's side made it difficult on the night.





"When it was 2-0 at half-time the gaffer told us it would be very dangerous and difficult because one goal can change everything," said the defender.





"If they scored then they would have some power and incentive to try and equalise. But we were able to stop them scoring then we got a third. It was 3-0 but not easy.





"Obviously we knew that we could catch them out and we did that pretty well, especially in the first half - Gaston's goal was a result of it.





"The preparation for the game is always important and the work paid off."





Southampton loanee Ramirez stood out for Boro on the night after winning the penalty and scoring two goals, with his second coming from a stunning free-kick from 25 yards.





Kalas was full of praise for the Uruguayan, but was keen to share the plaudits with his teammates.





"Not just on Tuesday, Gaston's outstanding in training and every game," Kalas. "He's the kind of player that could win us promotion but it's about the team.





"We're working hard as a team and defenders to give him confidence by not losing the ball.





"I think he can feel that now and hopefully we can support him from the back and the players around him are creating space for him. He's outstanding and deserves everything."
