BARCELONA manager Luis Enrique has launched a stunning attack on the club's hierarchy after openly questioning the transfer policy during a press conference.

Enrique, who won the treble in his first season at the Nou Camp and the double last season, was clearly unhappy with decisions made by those above him.

The 46-year-old, who also won two Spanish titles, the Copa del Rey twice and the Cup Winners' Cup as a

Barca player, was clearly unimpressed with several key decisions.

His main contention was in allowing Brazilian right-back Dani Alves to leave on a free for Juventus after eight brilliant years at the Nou Camp.

Enrique said: "That was the first news that surprised me in the summer.

"I wish the best for Dani Alves, a unique, special and different player, a 100 per cent professional.

"He gave everything at the club and joined in everything. He was exemplary. I think Juventus have strengthened well.

"You remember that before we had thought Daniel renew the option that was and why we signed Aleix [Vidal]."

Alves played 48 matches in all competitions last season, compared to Aleix, who managed just 14.

The Spaniard will likely start the season as first-choice, although Lucas Digne was also signed from Paris Saint-Germain after an impressive season on loan at Roma.

The coach added that he may have to change his style of play without Alves to overlap.

Enrique also took the opportunity to remind Bartomeu that he wants to keep a pair of players who have been linked with leaving the club this summer - Arda Turan and Javier Mascherano.

"I am very happy with Arda Turan's performance," added Enrique.

"Taking into account the situations of how he came [the transfer embargo] I appreciate it.

"Arda is special on and off the pitch. Remember the first year of [Michael] Laudrup at Barca, Luis Suarez. Players are not machines. They have to find their place.

"It is possible that in its first year he has added more inside than [what can be seen] outside. I have no doubt that Arda continue here. I want him to continue here.

"We have won titles. That will raise the level and I'm sure it's a matter of time."

On Mascherano, he said: "I take this opportunity to say that I hope the club renew his contract.

"I hope and wish, as there [are current negotiations] with Mascherano, that [they come to a resolution]."

Enrique also said that he was on the look out for another forward, but at the moment there are no obvious options - youngster Sergi Samper could see more game time.

"We looked for a striker, but if there is no option on the market we can sign someone else."

Enrique also hinted that the return of winger Pedro from Chelsea remains a possibility.

"If [the hierarchy] pay the clause... then we can negotiate."

The coach also spoke on what has been a tough summer for star man Lionel Messi, who missed a penalty in the final of the Copa America, retired from international football and was then sentenced to 21 months in jail for tax fraud.

"He [retired] at a difficult time.

"Time will tell whether or not [he will follow through with it].

"As a fan I would like to see him play with Argentina. As Barca coach I am open to any possibility."

He added: "Leo Messi will come as [prepared as he] has always been. He will have a longer vacation but I have no doubt that he will [return ready].

"I have zero worries about the Messi situation.

"I wish he would have won the Copa America but football teaches you that if you do everything right and you deserve sometimes do not get the goal.

"Football gives rise to speculation thousand.

"I think Messi's [performance will be] in line with previous seasons."
