Hello and welcome to Eurosport's LIVE text commentary of Barcelona's clash at Leganes in a top-vs-bottom encounter in La Liga. Leo Messi has been in top form in recent weeks but under pressure Ernesto Valverde needs his other players to step up a gear. Kick off is 40 minutes away.

FULL-TIME: Barcelona stretch their lead at the top of La Liga to three points with this somewhat fortunate victory at Leganes.

Save! Messi works the ball to Dembele but he's denied Barca's third by Cuellar who makes a fine save.

Yellow card! Vidal goes into the book for a cynical foul on Eraso.

Into the last five minutes and Barca are heading for a barely-deserved three points. This won't silence Valverde's critics but boy does he need the win.

Leganes subs: Now heading for a heartbreaking defeat, the hosts make a double change, with Rodri Tarin and Carrillo replacing Omeruo and Roque Mesa.

GOAAAALLLLLLL! Leganes 1-2 Barcelona: Vidal scores what could be the winner for Barca! But it comes in controversial fashion... Dembele's corner delivery takes a deflection and rolls kindly into the path of Vidal at the near post. He cannot believe his luck and finishes with aplomb. Leganes are demanding for the offside flag to be raised but VAR sees the ball hit off Perez and therefore the goal stands!

VAR check for a possible Leganes penalty! Strong appeals for a handball in the Barca box! Did the ball hit Umtiti's hand or hip? VAR is going to check... and no penalty is given!

Siovas is in some pain with a hand injury after colliding with Dembele, but Barca's resulting free-kick delivery is terrible.

He may have provided the equaliser, but Messi looks like he is nursing a hangover from the international break. When he doesn't tick, Barca don't tick.

Block! Fati instantly involved, teeing up Rakitic whose venomous shot is blocked by a home defender.

That switch means Barca have gone to a 4-2-4 in search of a much-needed victory. They have 20 minutes to find a second goal.

Barca sub: de Jong is replaced by Ansu Fati.

Barca are preparing their final change.

Chance! A rare opportunity for Leganes in the second-half goes unconverted! Silva dances his way down the left and his cross picks out Eraso, but he fails to hit the target from point-blank range!

Wide! Suarez swivels on the edge of the penalty area but shoots wide on the turn.

Firpo races to the far post to meet Messi's beautiful diagonal ball but can only side-foot it over the bar. His intention was to cut it back to Suarez in the middle but the technique wasn't right.

A draw today could see Barca fall as low as fourth-place this evening.

How goals change games; Barca are in complete control now and enjoying all the possession.

Barca subs: The disappointing Griezmann is replaced by Arthur Vidal, while Ivan Rakitic takes the place of Busquets.

Shot! De Jong steals the ball on the edge of the penalty area, poking the ball to Messi whose tame effort is straight at Cuellar.
