AC Milan star Clarence Seedorf believes Andriy Shevchenko will be able to put his Chelsea nightmare behind him and get back to his world-beating best as he returns to the San Siro. Shevchenko endured two disappointing years at Stamford Bridge following a big-money move from Milan but sealed a return to Serie A when the two clubs agreed a deal yesterday - although it is still subject to a medical tomorrow. Seedorf played with the Ukraine striker for four seasons at the San Siro and believes he will prove his doubters wrong as he returns to the scene of his greatest triumphs. 'Now Andriy will certainly be very motivated and he will have the desire to demonstrate that he is not that which we have seen in London and that he is a true footballer,' he said. The Blues signed the Ukraine international in the summer of 2006 but he failed to live up to his reputation as the world's finest striker. The former European footballer of the year scored just four league goals in the 2006-07 campaign and five last season as injuries and form undermined his impact in west London. Kakha Kaladze spent six seasons with Shevchenko, including one at Dynamo Kiev and is sure he will return to his best. 'I am happy to be able to embrace Sheva once again,' he said. 'For us footballers it is not nice to not find yourself in form, now Andriy can return to form with us.' Shevchenko will have a medical tomorrow and if all goes to plan he will link up with his new team-mates on Tuesday. The 31-year-old could make his long-awaited return to the Rossoneri team in the first game of the season - at home to Bologna on August 31. And Milan coach Carlo Ancelotti, the man who brought Shevchenko to the San Siro the first time around, is delighted to have the club's second-most prolific goalscorer of all-time at his disposal once more. 'I am happy to welcome back Andriy who Milan strongly wanted,' he said. 'I think he can be useful to us as he was in the past.'
