Lionel Messi, the top scorer in La Liga, has netted in each of his last five league games. This season he has notched more La Liga goals on his own (26) than Leganes have in total (25).

Barcelona boss Ernesto Valverde: “I’m expecting the Leganes we've seen for the whole season. They're a team with enthusiasm, they play very well and it will be a tough match. We want to get the three points, we need 15 to be champions.

“I expect a game similar to last season. They will try to surprise us on the counter attack."

On the chance to equal the La Liga unbeaten record: “We don’t have these figures in our head even though it is an important achievement."

Leganes are only in their second La Liga season ever and are brilliantly nicknamed the cucumbers.

They are 14th in the table, but in no danger of relegation.

Coach Asier Garitano said: “We need to play a great game, and though it will be a challenge for us, we have to go for it.

"I think Barcelona are going to rotate as they have a lot of games. Let’s see if we can compete there."

Barcelona make four changes from the 4-1 win over Roma. Philippe Coutinho, who was ineligible in the Champions League, Ousmane Dembele, Andre Gomes and Thomas Vermaelen start.

Sergio Busquets is injured again, while Andres Iniesta, Samuel Umtiti and Jordi Alba drop to the bench.

Two switches for Leganes from the 1-0 defeat by Valencia. Nabil el Zhar, once of Liverpool, and Raul Garcia start. Diego Rico is banned and Ezequiel Munoz is on the bench.

Thirty down, eight to go.

That's how close Barcelona are to becoming the first team to ever go through a long La Liga season unbeaten.

The feat has not been achieved since the 1930s when there were 18 games in a campaign.

A win or draw today equals the La Liga unbeaten run of 38 games - set by Real Sociedad from 1978-79 to 1979-80.
