Paul di Resta says he remains fully focused on the job at hand, despite speculation about his future prospects in F1. In recent weeks, the Scot has found himself linked with Ferrari after Sir Jackie Stewart said he would be a \'very good target\' for the team [See separate story HERE] and then emerged as a possible target for Mercedes if Michael Schumacher decided to retire at the end of the year [See separate story HERE]. The Scot has enjoyed a solid start to the 2012 season with Force India, with three top ten finishes including a fine sixth in Bahrain but despite the rumours about his future and the desire to be a championship winner, di Resta said his current focus was very much on the job at hand. \"It\'s always nice to have the press interest and people looking out for you,” he told Sky Sports News, “but I need to stay focused on doing the best job I possibly can. \"It\'s no secret that I want to be a race winner and World Champion - and to do that, I need to be in a great car.\"
