Arsenal boss Unai Emery has recommended Tottenham rival Mauricio Pochettino for a job in the past.
Emery was so impressed with a young Pochettino that in 2012 he told Valencia chiefs the then-Espanyol boss should replace him when he left for Spartak Moscow.
Pochettino said: “The Valencia chairman called me and said, 'I want you in Valencia'.
“We were talking and he said, 'Unai Emery advised me and told me to pick you, you are the best manager' and I said no, to stay in Espanyol. Then I called Unai and said, 'Thank you very much for recommending me.' I chose to stay at Espanyol at the time. [I am] loyal.
“You need to ask him why he picked me. I think there is no point to talk about that.
“You need to say thank-you and be grateful when a colleague – and after, someone who became a very good friend – [does that]. It's not usual that a manager recommends another manager when he leaves the club."
