Mauricio Pochettino says playing against Barcelona motivates him and he also accepts he will never manage the Spanish champions.
Tottenham host Ernesto Valverde's side in Wednesday's Champions League group stage match at Wembley and with Pochettino being a former player and manager at rivals Espanyol, the Spurs boss is relishing the tie against the La Liga giants.
"[Facing Barca] motivates me, being an Espanyol fan and living for so many years in Barcelona," the Spurs boss told Spanish tabloid Marca.
"It is more than understood [that I will never take over]. My path and that of Barcelona are different, opposite directions. Coaching there would be impossible."
The Argentine added: “Winning a game is always nice and when you win against Barcelona, even more so, because that would mean something important for us.
"For me, (Lionel) Messi is still the number one (player in the world) and will be until he retires."
