LONDON, England - Paul Hembery has apologised after hitting back at comments made by Fernando Alonso after the 2013 Korean F1 GP.Spaniard Alonso had questioned the "quality" of Pirelli's 2013 tyres so Pirelli boss Hembery hit back. He said at the time: "I can only suggest he goes to ask the soon-to-be four time champion how to get the best from the same tyres."'HE APOLOGISED'Ferrari's Alonso was quoted by the Brazilian newspaper O Estado de S.Paulo: "We invited Paul for a chat. He accepted, he came, he apologised and we understand (each another) now."It seems strange with the season they are having that they speak up, but, as I said, he apologised."Alonso, however, insists that the mid-season change of tyre construction particularly hurt Ferrari's performance and added: "Force India is now struggling for points. I also remember Sauber struggling not to be out of qualifying in Q1, and now they're fighting out the front of the race."Ferrari boss Stefano Domenicali wa quoted as have seen both sides of the story. "It is important to take the complaints of drivers seriously to help Pirelli do a better job," he told Speed Week, "but I also see Pirelli's position, because if they are not given the chance to test, that's not right."
