Lionel Messi continued his remarkable run of form with a second-half double as Barcelona continued their march towards the La Liga title on Saturday with a 2-0 win over Espanyol. The visitors gave their city rivals a tough game at the Camp Nou, but Messi's chipped free-kick with 19 minutes to play and a late second sent the reigning champions 13 points clear at the top ahead of second-placed Atletico Madrid's game at Alaves later on Saturday. Messi has now netted eight times in his last four games for Barca, and leads the way in the La Liga scoring charts with 31 goals, 13 ahead of teammate Luis Suarez. "I had no idea he would hit (the free-kick) like that," said Barcelona coach Ernesto Valverde.

"I would love to say that we had planned it, but it's not true, it's up to him. He didn't need my opinion and he scored." It was a fitting way for the Argentinian to mark his 675th Barcelona appearance, which moved him ahead of Andres Iniesta into second on the club's all-time list -- 102 adrift of Xavi Hernandez. He made a low-key return to international action in midweek as Argentina lost a friendly to Venezuela, but Valverde was delighted it did not affect Messi on Saturday. "Messi is the same player no matter what team he is playing in," he said. "He would be the same if he played in Australia... We are delighted to have him, it's a luxury for me to coach him."
