Inter Milan's signing of CSKA Moscow attacking midfielder Daniel Carvalho has stalled.

Inter had expected to sign the Brazil international as a free agent next month, but it's emerged his contract carries a clause which means he could be tied to CSKA until December 2008, says Gazzetta dello Sport.

The move is still on for Carvalho, but Inter are spending today discussing a fee with CSKA officials as they prepare to welcome the 24 year-old for a medical.
