David Nalbandian will be looking to regain his form at the ATP Masters 1000 event in Key Biscayne Miami this week. Nalbandian was expected to have a good run in Indian Wells last week but he suffered a shock defeat to the Austrian Jurgen Melzer. David Nalbandian’s 2009 season was plagued by a hip injury and he was sidelined for 8 months of last season. The Argentine is widely regarded as one of the most talented players never to have won a Grand Slam title. In 2007 Nalbandian won back to back Masters 1000 titles in Paris and Madrid, and he managed to beat Federer and Nadal both times. Nalbandian reached the final of Wimbledon on his grass court debut in 2002 but lost to Lleyton Hewitt in the final 6-1 6-3 6-2. If Nalbandian can find his best form then he still has a chance of winning a Grand Slam title.
