Celtic and Everton are on alert after Spartak Moscow revealed they will listen to offers for Irish winger Aiden McGeady. The 27-year-old left Celtic in 2010 to join the Russian side in a deal worth £9.5m, but has in recent times spoken about his desire to return closer to home. Spartak's general director, Roman Askhabadze, admitted the club are willing to let McGeady, whose contract expires at the end of the season, leave for the right price in January. "The club is willing to discuss a new contract for Aiden at any time," he told a Scottish national newspaper. "But if we get a good offer this winter, we would be willing to consider it." Everton boss Roberto Martinez was keen to bring McGeady to Goodison Park in the summer, but failed to secure a deal before the close of the transfer window. News of Spartak's stance is likely to reignite the Toffees desire to sign the Republic of Ireland international, but will almost certainly face competition from Celtic for his signature.
