DPMM FC have enjoyed an excellent start to their campaign since returning to the S.League and are currently top of the table, just ahead of Harimau Muda.
The 2012 season has been fairly open so far, with traditional giants Tampines Rovers, Home United and SAFFC enduring indifferent early form, while less-illustrious sides like Balestier Khalsa and Hougang United have made impressive starts.
However, the Bruneian outfit coached by Vjeran Simunic look the real deal, boasting quality in all areas of the field.
In goal they have Wardun Yussof, who has established himself as one of the best shot-stoppers in the league, and he is ably protected by the imposing Tales Dos Santos and his centre-back partner Shahrul Rizal Rahman.
Captain Rosmin Kamis provides plenty of grit in the middle of the park, while the playmaking duties are ably carried out by Croat Ivan Jerkovic, who has S.League experience from his time with SAFFC.
Nonetheless, it is up front where DPMM's main threat stems front, with Grahl part of a formidable attacking trio that also includes Ghanian Basiru Osman and Bruneian Shahrazen Said.
Despite being 35 years old, Grahl still possesses a good burst of pace and is exceptionally adept and making darting runs in behind opposition defences.
However, having honed his trade in the Brazilian and Japanese top flights, it is his experience that is his most lethal weapon.
He analyses the game very well whenever he isn't directly involved with the play, and seems to be the first to react whenever the ball drops in his vicinity. Already, he has shown signs of a strong understanding with Osman and has displayed his lethal finishing ability on a number of occasions.
This was best exemplified in DPMM's 1-1 draw with Harimau Muda on March 22 when he submitted his contender for goal of the season. Racing onto a long ball on the left-hand side of the box and without even taking a look up, Grahl swung his left boot at the ball and unleashed a ferocious shot into the top corner, leaving Young Tigers goalkeeper Izham Tarmizi rooted to the spot.
This week, DPMM entertain basement side Courts Young Lions, who only just picked up their first point of the campaign last Sunday against Balestier Khalsa. With Robin Chitrakar's young charges short on experience, Grahl could just be the man to put them to the sword.
