The Argentine ace broke new ground yet again with his goal against Celta, earning the praise of his coach, who also acknowledged Eric Abidal's comeback after his liver transplant
The 25-year-old broke new ground by being the first player in the history of Spanish football to register a goal in 19 consecutive league games - ensuring he has also scored against every other Primera Liga side in successive games this season.
And Roura revealed his delight for the Argentine's scoring heroics, telling reporters: "Messi's record of scoring against all opponents in a row? That no one has done it till now shows how difficult it is."
Messi's milestone was not enough to hand the league leaders victory however, with Borja Oubina's late strike ensuring the hosts shared the spoils on the night Eric Abidal made a long-awaited return onto the substitutes' bench.
"We had worked hard to turn the score around in the first period, and maybe at the end we lacked the intensity to prevent them from scoring their equaliser," Roura continued.
"Cristian Tello is someone who can offer something different to the team. He works hard, and still has a lot more margin to grow.
"Abidal is part of the match squad now, meaning he's ready to play."
Though the Frenchman was included in the Blaugrana's squad for the first time since undergoing a liver transplant last year, he is not anticipated to be fit for his team's upcoming Champions League quarter-final date with Paris Saint-Germain.
