Barcelona midfielder Arturo Vidal said superstar captain Lionel Messi is "from another planet" after producing a masterclass performance against Real Valladolid.

Messi was at his trademark best with a brace and two assists as LaLiga champions Barca routed Valladolid 5-1 at Camp Nou on Tuesday.

Argentina international Messi set up Vidal with an exquisite pass before scoring a stunning free-kick – the 50th of his career for club and country – prior to half-time.

Messi netted his second of the match after the break and teed up Luis Suarez as Barca moved top of the table.

"It makes a difference with Leo giving all his quality. When he's like this, the team feels it," Vidal told Movistar Plus.

"We see him every day, but he surprises us every day. Leo is from another planet. 

"We are happy, we won and the team felt good. I have no words to talk about Leo. You have to take advantage of it and make the most of him."

Although Clement Lenglet's second-minute opener was fortuitously cancelled out by Valladolid's Kiko Olivas 13 minutes later, Messi was able to inspire Barca against the visitors.

Barca are two points clear of Granada and Atletico Madrid – the latter of whom have played an extra match due to the postponement of El Clasico last weekend – after 10 games.

"These victories help you, but you have to keep improving," Vidal, who has been linked to Serie A outfit Inter, added. "The game against Slavia [Prague in the Champions League] is not what we know how to do. Hopefully it won't happen to us from now on."
