The Argentine forward feels that Barca deserved more than a draw at San Siro, as he partially put the blame on the pitch for their inability to break the deadlock
The Catalans created a number of chances to open the scoring, but failed to find the net at San Siro, and Messi feels that the poor condition of the pitch made things difficult for Barca.
"It was a tough match that we should have won. We played our game but it was difficult because of the pitch, and because they [Milan] are very strong," Messi was quoted as saying on the club's official website.
The Argentine then admitted that the Blaugrana face a perilous scenario in the return leg at home as the tie remains delicately poised.
"It’s a dangerous situation. Either team could go through, we hope we can score in the return so it will be us. We deserved to win [the first leg]."
The second leg takes place at Camp Nou on April 3.
