Andy Murray will be seeking another convincing win over Joao Sousa in Wednesday's second round clash at the Dubai Duty Free Championship.

The British No 1 was pitted against the Portuguese player at the Australian Open last month, where he eased into the last 16 with a straight sets victory.

An impressive opening win over Gilles Muller suggested that Murray has ironed out the unforced errors which led to last week’s surprising defeat against Gilles Simon.

But tougher tests lie ahead for the Scot as he targets his first ATP Tour title of 2015.

Top seed Novak Djokovic shed some rust in an opening win over Vasek Pospisil and will resume his campaign against Andrey Golubev.

Djokovic, returning after his Australian Open triumph, was briefly troubled by Pospisil in a 6-4 6-4 win, but should make short work of his Kazakh opponent.

Defending champion Roger Federer started the defence of his title with a ruthless win over Mikhail Youzhny, setting up a tricky next match against Fernando Verdasco.

The Spaniard impressed in a 7-5 6-1 win over compatriot Guillermo Garcia-Lopez and could be a potential stumbling block.

Tomas Berdych, another seed, also returns to action with a clash against Italian Simone Bolelli.
