Aleix Vidal has once again been left out of the squad

On the other hand, FC Barcelona continue to be interested in signing Borussia Dortmund centre-back Mats Hummels.

Aleix Vidal, one of the signings made by FC Barcelona this season, has once again been left out of the squad by Luis Enrique.

Unless there is more news later, it appears the former Sevilla man has been omitted for technical reasons. A surprising decision, given Barça’s current problems at right-back, with Dani Alves’ form and off the pitch behaviour under the microscope. 

What has happened? For now, no-one can find an explanation. However, the numbers show that, at the moment, Vidal, who was signed to cover Alves when absent, is last place in the full-back rankings.

Luis Enrique prefers Sergi Roberto, a midfielder playing out of position, to him. This was shown in the defeat to Valencia. 

As we wait for an official explanation, facts demonstrate that Aleix Vidal could be one of the players Luis Enrique was referring to when asked about the Marc Bartra’s case.

We don’t know if his case, though, has been influenced also by his famous appearance in a Gerard Pique Periscope, when he joked about being a substitute. Whatever it is, it seems clear he has lost Luis Enrique’s faith.

On the other hand, FC Barcelona continue to be interested in signing Borussia Dortmund centre-back Mats Hummels, as they look to bolster their defence for next season.

The German defender has been on the Spanish champions' shortlist for a number of years, and while ex-director of football Andoni Zubizarreta tried to lure him to the Camp Nou while he was at Bayern Munich, he eventually chose Dortmund in 2009 following a short loan spell.

According to German newspaper Bild, FC Barcelona continue to track the 27-year-old, whose contract expires in 2017 and are likely to make a summer move.

FC Barcelona's current technical director, Roberto Fernandez, is said to be extremely interested in the services of the German, but FC Barcelona will have to hold off stiff competition from the likes of Manchester United and Arsenal.

Neymar will stay at FC Barcelona

Josep Maria Bartomeu insists Neymar will not be leaving Barcelona, despite interest from many sides, including PSG. 

"If someone wants to negotiate with Neymar, we will not give them permission," he told Globo Esporte. "Neymar will stay at FC Barcelona."

The reaction came after one of Neymar's representatives, Wagner Ribeiro had spoken to L'Equipe, saying Neymar would like to live in Paris. "Neymar has a contract with Barca until 2018," Ribeiro said. "He feels good in Barcelona, he's loved over there and he's playing for the best team in the world. It's no small feat to impose yourself at such an enormous club.

On the other hand, Luis Suarez says FC Barcelona will be 'relaxed' in the second leg of their Champions League quarter-final against Atletico Madrid. The striker, who netted two goals to win the Blaugrana the first leg after Fernando Torres opened the scoring, spoke on Spanish television after the game.

"The return will be a similar game to today’s," he said. “But we are relaxed as we they will be obliged to attack to win the game. If we score one, they will have to score two."

Luis Suarez admitted this was a tricky game but Torres' first-half red card led to FC Barcelona gaining a big advantage. He said: "Obviously a sending off in the first will affect the game, even more when it’s a great player. Everyone knows his quality, but he made two heavy fouls. It was a pity - I would have liked to come back with 11."

To end, Gerard Pique gave an interview to his former Manchester United team-mate and current BT Sport collaborator, Rio Ferdinand. Among other topics, Lionel Messi came up. Ferdinand asked who was better, the Argentine or Cristiano Ronaldo, and Pique had no doubts.

"Both are impressive, we are talking not just about the best players not just in this moment, but in history," said Pique. "I always say the same, for me, Messi is not human, while Cristiano is just the best among the humans."
