Chelsea boss Jose Mourinho is a fan of Tottenham counterpart Mauricio Pochettino.
Tottenham manager Mauricio Pochettino was working in Spain at the same time as Mourinho, and the two men get on well, according to the Portuguese.
"We respect each other, we've known each other for a long time," said Mourinho. "We cannot be close friends because, to be close friends you have to have a certain kind of relationship. But we are friends. We have good feelings for each other.
"Also his technical staff and my technical staff have known each other for a long time too, so relations are very good. It's the kind of match where the fourth official will have a peaceful time because we are very happy to be seated almost together.
"We met a couple of times after he left Espanyol, when he was preparing himself for the next step. In that period we met a couple of times, but nothing important."
