ATP Masters Cup - Shanghai

The ATP's season-ending tournament for the world's top eight players begins this Sunday.

RED Group: Roger Federer, Andy Murray, Andy Roddick, Gilles Simon.

This is an interesting group with the two Andy's and Federer competing for the 2 places in the semis. I don't think Gilles Simon, who was added to the field after World no 1 Rafael Nadal withdrew with a knee injury, will trouble the other 3 from the group.

Andy Murray is in top form this year defeating all the top players of the world. If he continues his form, he should easily sail through to the semis. Federer has also been in good form lately but has been affected by some injury issues. I expect Murray to defeat him but he should be able to defeat Roddick and Simons easily. Roddick for me doesn't have the game to compete with Murray and Federer. So from this group, I'll pick Murray and Federer to reach the semis.

BLUE Group: Novak Djokovic, Nikolay Davydenko, Del Potro, Jo Wilfred Tsonga.

This group looks more open than the Red group. At the beginning of the year, Djokovic was considered as a threat to Nadal and Federer. But as the year, progressed he faded away. So, he has much to prove here. Tsonga and Del Potro have been in good form lately, I expect some good performances from them. Not quite sure how Davydenko will do. So from this group, I'll pick Tsonga and Djokovic to reach the semis.

My Prediction: Federer or Murray should win this year.
