Manchester City boss Manuel Pellegrini won't take FA Cup opponents Middlesbrough lightly.
Middlesbrough are managed by Aitor Karanka, who joined Real Madrid as assistant coach following Pellegrini's sacking at the Bernabeu in 2010.
"I expect a very good game," said Pellegrini. "Middlesbrough are in a very good position in the Championship and working with a very good manager.
"I know him well and I am sure that if we don't play with 100 per cent intensity and concentration we are going to have problems to qualify to the next stage."
