Chelsea have secured international clearance for loan signing George Weah, making him available for selection for tonight's Premiership clash with Tottenham. Chelsea boss Gianluca Vialli, who signed the Liberian international on loan from AC Milan yesterday until the end of the season, today revealed he was delighted with his transfer coup. Vialli told ClubCall, "He's a great player - one of the most famous and prolific strikers in the world - and he's a winner. He's not the youngest but he's still really fit. I think it's a great thing for Chelsea. He can help our strikers to play better and our strikers to score more goals. We were quick and determined to sign him. A lot of clubs around Europe wanted to sign him but Chelsea were quicker."
