PA PhotosLatics owner Dave Whelan claimed on Wednesday that the north west club had rejected a third attempted deal from Chelsea as their £5million bid fell short of Wigan's valuation for the 21-year-old forward.
Di Matteo, who is with Chelsea on their pre-season tour in the United States, told SkySports.com: "(It's) something that the clubs are discussing but at the moment he is a Wigan player.
"He had a good season last season, he is young and an interesting prospect."
Moses, who scored six goals last season, only has one year remaining on his contract and has not yet signed a new deal to keep him at the DW Stadium.
