AS Roma president James Pallotta admits he was disappointed by a swipe from Radja Nainggolan.

The midfielder left Roma for Inter Milan over the summer.

And he stated: "In Roma the president comes once a year, at Inter there is a management prepared and present."

In response, Pallotta stated: "I loved Radja, I care a lot for him and I'm sorry to hear him say things, he says I'm never in Trigoria but I'm working every day on Roma, for example several club leaders came to Boston this week."
