Lionel Messi plays the ball through to Ousmane Dembele and Luis Suarez. Dembele is onside, Suarez is offside. Unfortunately for Barca, the Frenchman leaves the ball for the Uruguayan. His shot is saved and then the flag goes up anyway.

Ruben Perez fires one over from distance for Leganes.

A break in play as two Barcelona players help the referee to reattach some of his communication gear.

Good reaction from Leganes, who have a half-chance and then a corner - but Barca get it away.

That's the sixth consecutive La Liga game that Lionel Messi has scored in. He is five goals above Luis Suarez in the golden boot race.

Lionel Messi is fouled by Dimitris Siovas about 30 yards out, he can have another go now.

It's not one of Lionel Messi's better efforts as he puts it into the wall. I've seen him score free-kicks over the wall, around the wall and under the wall. But straight into the wall is never going to work, whether you're the greatest player of all time or not.

Barcelona are turning the style on now and Luis Suarez is fouled just outside the box. It's Lionel Messi territory.

Ivan Cuellar pulls off a wonderful save to keep Barcelona out - but the Catalans should really be ahead.

Lionel Messi is about 10 yards out but instead of shooting he squares it to Luis Suarez. It looks like a straightforward finish from the Uruguayan - but somehow the keeper reacts quickly stops it. But Suarez shouldn't have given him a chance.

Barcelona's best chance. A long ball is lofted into the box, Luis Suarez holds off his defender and then prods a first-time shot which goes just wide.

A good minute or more of possession results in Philippe Coutinho shooting - but Leganes keeper Ivan Cuellar dives to save the effort at his near post.

A long ball over the top almost catches Barca out but Gerard Pique shepherds it back to Marc-Andre ter Stegen.

John McEnerney: Barcelona finally have the back four sorted. They were flakey enough in the early part of the season, Umtiti has been immense and Vermaelen at last injury free can slot in when needed. The visit of Real Madrid might the be the one to break the unbeaten streak, they’re firing of late. Home win

Ousmane Dembele's cross is cleared to Andre Gomes, whose first-time shot is blocked. First shot of the game.

The Cucumbers have lost all three previous meetings with Barcelona. They had never met before last season, Leganes' debut La Liga campaign. The three meetings so far have been 5-1, 2-1 and 3-0 wins for Barca.

Good defending by Unai Bustinza to deny Philippe Coutinho. Luis Suarez picks out his former Liverpool team-mate, who tries to take on the Leganes defender and fails. The Brazilian goes to the ground and the ball goes out for a goal-kick.

Slow start at the Nou Camp - neither side to have a meaningful attack.

Barcelona want a corner early on as Sergi Roberto picks out Luis Suarez. He loses the ball but thinks a Leganes player got the last touch. Ref says goal-kick.
