Boro Head Coach Aitor Karanka says he has good memories of playing Millwall ahead of Saturday's clash at the Den.

Karanka's team were 2-0 winners in this fixture last season, and the Spanish boss said he is looking forward to another trip down south to face the Lions.

"I have good memories of playing against Millwall at the Den," said Aitor. 

"A lot of people told me how difficult it is to go and play there but I have good memories because it's the game that started our good run last season. 

"We started to win more games after then and I think we went five or six without losing after then. 

"I would like to repeat that form but I know it's going to be a very difficult game."

Millwall are currently two points off the Championship relegation zone, but Aitor says he is anticipating another tough game against a strong Ian Hollway side.

"Millwall are the kind of team that if you go there thinking it's going to be an easy game because of their position in the table then you are making a very big mistake," said Aitor.

"We have to go there thinking it's going to be a very difficult game because they are a very tough team."
