Andres Iniesta believes that Gerardo Martino is the best option for Barcelona, despite speculation that he will leave in the summer.
Celta coach Luis Enrique is reported to lead a list of potential replacements for the Argentine, who only took over from the late Tito Vilanova last summer.
A campaign which saw the Catalans exit the Champions League at the quarter-final stage, lose to Real Madrid in the Copa del Rey final and fail to dominate in La Liga have seen Martino under heavy scrutiny, but Iniesta leapt to the defence of his trainer.
"For me, the coach that we have now is the best," the Spain international said to Diario Ole. "Also, I would be delighted if he stayed here for longer and showed everyone what he can do.
"The first year is a difficult one for everyone. I have always seen him with the desire and determination needed. He always believes in our chances.
"Things don't always go how you want them to but you have to try. The world of Barcelona is always difficult, not just for him but for everyone and for us players as well. There is a constant high demand and you have to be ready for it.
"We have failed as a team at important moments. Sometimes things don’t go how you want them to.
"This isn't because you don't want it, it's just how it goes sometimes. You always need to be making changes, regardless of whether you are winning trophies or not."
Barca visit Elche on Sunday aware that a win would mean that they host fellow title contenders Atletico Madrid on the final day of the season knowing that victory would see them defend the title on head-to-head record.
