Roma midfielder Radja Nainggolan has distanced himself from a summer move to Premier League leaders Chelsea by declaring himself happy at the Serie A side.

He has also spoken frankly about smoking cigarettes amid reports he was recently dropped by Belgium coach Roberto Martinez because of his habit.

The midfielder is currently on international duty with Belgium but has been left out of their recent squads in the aftermath of the European Championships in France last summer.

'I'm not ashamed because I smoke and I've never hidden this habit of mine,' Nainggolan told reporters outside the Belgium training camp.

'I know I should set a good example, I have kids… But I'm just a footballer, I do my job. Everyone knows that I smoke and I can't hide it, but I'm not ashamed.

'I was disappointed not to be called-up after a good European Championships. I'm someone who bluntly says what he feels, so I never made a secret of my disappointment.

'The Coach must have had his reasons not to call me, but now I'm looking forward.'

Nainggolan has become one of Europe's hottest properties after scoring 12 goals this term to propel Roma to second in the Serie A table.

However, in quotes reported by Gazzetta.it, the 28-year-old played down speculation linking him with a move to England and in particular Stamford Bridge.

'In Rome I'm fine,' said Nainggolan.

'My family is happy and even the weather is often good.

'Sometimes you make choices for the money, others for the quality of life, which matters a lot to me. Also, if I went to England, I would have to start from scratch, but I repeat: I am very well in Rome.

'China? Currently no, but you can never say never. We need to see right now.'
