UEFA has repeated the need for European football clubs to meet its new financial fair play regulations, following the close of the January transfer window.

In England alone, Premier League clubs spent a combined total of more than £200m during the month-long window but will be required to 'balance the books' at the end of the season. According to UEFA, recent transfer activity will start to an impact on clubs required to break even in the financial years ending 2012 and 2013.

A spokesperson said: "The clubs know the rules and also know that UEFA is fully committed to implementing them with rigour. "As from this summer all payments due on transfers and to employees will be assessed by the Club Financial Control Panel as part of the "enhanced overdue payables" rule."
