Hulkenberg calm amid Ferrari switch rumours

Nico Hulkenberg has described as "speculation" reports he could be headed to Ferrari to replace Felipe Massa in 2013.

After taking some time to settle back into racing this year following a season on the bench, the former Williams driver has impressed at Force India in recent grands prix.

"That (early struggle) has changed and now I am fully comfortable," he said ahead of this weekend’s Belgian grand prix.

Reports have even mentioned Hulkenberg, 25, as a possible contender for struggling Massa’s cockpit alongside Fernando Alonso.

"That’s all speculation and it wasn’t me who put it on the table," he is quoted by SID news agency at Spa.

"It’s nice when you get good press, but I’m just concentrating on my job," added Hulkenberg.
