Since opening his Champions League tally against Greek side Panathinaikos in November 2005, Lionel Messi has been the stuff of nightmares for almost every team he has crossed paths with.
The forward has bagged 100 goals in UEFA competitions (97 in the Champions League and three in the UEFA Supercup) and he continues to shatter records. Arsenal, who have conceded nine goals at the hands of the Argentine, have become his favourite victims.
Seven clubs have achieved the impressive feat of stopping Messi from scoring: Atletico Madrid, Benfica, Chelsea, Inter Milan, Liverpool, Rubin Kazan and Udinese.
The Barcelona superstar has been given another chance to tick one of the names off the list with Barcelona pitted against Chelsea in this year's Champions League round of 16.
Having faced the Blues eight times before, Messi has failed to find the back of the net and is hoping to end this particular drought on Tuesday. If not, a new chance awaits in the return fixture at the Camp Nou.
