Tito Vilanova's assistant had nothing but positive words for the attacking midfielder, while he was equally pleased with the team's performance
The creative midfielder netted one and set up another one in Sunday's encounter to help the Catalans to a comfortable home victory, and Roura was impressed with the Spain international's performance.
"He played at an extremely high level. He plays with such ease, he makes football look so easy. This is what makes him great," Roura said at a press conference.
The Barcelona coach then went on to voice his delight with the team's display in general as he feels the table-toppers were in extraordinary form.
"It was an unusual time to play but we had a party in the stadium. The players were at an extraordinary level. They were intense from the first minute."
Barca currently sit first in the league table, holding a 12-point lead over second-placed Atletico Madrid.
