The mercurial Messi became the top scorer in La Liga history

with a treble in a 5-1 hammering of Sevilla on Saturday and the Argentina talisman revelled in his latest milestone.

"Achieving this record in a competition like this is a wonderful thing. But, beyond that it was a very important game," said Messi, who now has 74 Champions League goals.

Luis Enrique's side face French champions Paris Saint-Germain at Camp Nou next month knowing a win would ensure they finish top of the fifa 15 coins group and Messi is determined to achieve that goal.

Emirates has already announced it is not renewing its sponsorship and Valcke said he "would be surprised" if Sony extended its deal, which expires at the end of this year.

"Both Sony and Emirates have nothing to do with the situation we are facing these last days," Valcke said, referring to the fallout from the bidding corruption report compiled by prosecutor Michael Garcia.

"I know that football is still a very strong product and I am not really concerned with FIFA's finances for the future."

But, speaking in Belfast after a meeting of the International Football Association Board, Valcke acknowledged the immediate future is not bright for FIFA's global standing while insisting "we are doing a great job."

"The image of FIFA is something I agree, over the last two weeks I would not say reached the bottom, but has reached a level which is definitely a level which we will not go lower than," Valcke said.

"Things are happening, things have happened, but we are still doing a lot of good things. We have to rebuild this image day after day. It's easy to destroy the reputation. It takes one second. It takes years to rebuild our reputation, but that's what we will do."

Sepp Blatter, the magnet for much of the criticism directed at FIFA, is seeking a fifth four-year term as president in May.

Much of that criticism  particularly from FIFA's own executive members  has centred on Blatter keeping Garcia's full 430-page report into impropriety during World Cup bidding confidential. Blatter received a further demand for Garcia's investigation to be released from the British government on Tuesday.
