Tottenham boss Mauricio Pochettino admits his Espanyol background makes him more determined to beat Barcelona.
Spurs face Barca in their next Champions League clash this week and Pochettino admits the prospect excites him.
"Of course," he said. "It motivates me being a 'perico' and living so many years in Barcelona. Going back to the city is always something nice and playing against Barça, too. It is always motivating.
"For me, (Lionel) Messi is still number one and will be until he stops playing.
"Talent, determination makes him, today, the number one in the world."
