Sneijder has been suffering from cramp since helping guide the Netherlands through to their third World Cup showpiece by beating Uruguay.

But the 26-year-old Inter Milan midfielder has given coach Bert van Marwijk a huge boost by declaring himself fit.

Goalkeeper Maarten Stekelenburg has recovered from a hip injury and will maintain his position while Gregory Van der Wiel and Nigel de Jong are back in contention for a start after serving one-match suspensions.

“It’s unbelievable, the most important match in my football life. It is quite something and this applies to all my players,” said the coach.

“No Dutch player has ever become world champion and that is extraordinary but we approach it as a special match.”

The Dutch, he said, must be brave in a match between teams with the desire to play attractive football.

“They have to be themselves and have to have the courage to play football against Spain,” said Van Marwijk.

“They are two of the best teams and I emphasise the word ‘team’.

“We beat Brazil and Spain beat Germany. Spain have played more attractive football than we have but the teams have the intention to play in the same way. Both teams have their own style but they resemble each other.

“I’m not going to tell you how I’m going to play. We just have to be ourselves.”

Van Marwijk rejected the notion that Holland had an advantage because they had won all their six matches while Spain had lost to Switzerland in the group phase and scored more goals, 12 to Spain’s seven.

“Spain is the best football country of the last few years,” he said.

“Scoring goals is unimportant now. This is a new match, a special match. We have lots of players who can score a goal and so do Spain. We have got to believe in ourselves and not be afraid. We are convinced we can win.”

Meanwhile, Dutch captain Giovanni Van Bronckhorst admitted he had dreamed of lifting the trophy in what will be his last football match, having announced his retirement.

He said: “As a boy I remember Maradona and Cafu and Dunga holding up the trophy. It is a dream to hold up that trophy. It would be fantastic for me, the Dutch team and the Dutch people to take it home.

“The only thing that counts is winning the final and we will walk on the pitch tomorrow believing we can do it.”

The Dutch midfielder has attracted interest from a number of clubs after putting in some impressive performances at the World Cup in South Africa.

Sneijder is currently preparing for the final of the competition as Holland take on pre-tournament favourites Spain in Johannesburg on Sunday night.

The Inter midfielder is currently joint top goalscorer at the World Cup and could win the golden boot award if he scores and Spain’s David Villa fails to find the back of the net.

United are just one club that have been linked with a move to buy the 26-year-old however Ferguson has refuted claims the club have had an offer rejected for the player.

He said: “I don’t know where those reports about Sneijder came from.

“How can anybody turn me down when I haven’t even made a bid?”

“I believe the squad is stronger than last season with the younger players having another year under their belts,” he added.

The United manager has also denied claims that the Old Trafford club are lining up a bid for Wolfsburg’s Mesut Ozil who has also had an impressive World Cup with Germany – who finished in third place in the tournament after they beat Uruguay 3-2 on Saturday.

Sneijder could win his fourth trophy this season after helping Inter Milan win a domestic double and the coveted Champions League title and a World Cup trophy would complete a stunning season.

Jose Mourinho, who led the Italian giants to an astonishing season, has moved on to Real Madrid and it is now former Liverpool boss Rafa Benitez’s task to keep hold of their key players ahead of next season.

Manchester City and United have both been linked with Inter striker Mario Balotelli, who was not a regular first-team player under Mourinho.

The 19-year-old has revealed his admiration for both Manchester clubs and could be tempted by a move to the Premier League if Benitez does not offer him regular football.

United begin their Premier League campaign against newly promoted Newcastle United as the club look to win back the top flight title from rivals Chelsea (Manchester United 1/5, draw 9/2, Newcastle United 11/1).
