Just when Celtic fans thought it was safe to feel happy about Champions League qualification, the president of Marseille provoked a bit of anxiety.
Celtic's name was barely in the pot for the group-stage draw when Hoops supporters were reminded that Moussa Dembele, a star of their European campaign last season, might not be around to excite the Parkhead faithful again this time around.
The Ligue 1 club are one of many to be linked with the 21-year-old hitman this summer, and their president Jacques-Henri Eyraud admitted his admiration for the young hitman.
The French starlet might be injured until September, but Celtic boss Brendan Rodgers should definitely consider the possibility of losing him before the window closes next week.
The 27-year-old striker, who bagged 27 Championship goals over the past two seasons, is available for transfer, with the Terriers wanting around £8 million for him, according to a report in The Mirror back in June.
Wells's prolific history in League One and the Championship should indicate that he would have no problem against Scottish Premiership opposition and, if Dembele leaves, the former Liverpool boss should consider bringing him to Glasgow.
According to bookmaker Bet Victor, Ibrox outfit Glasgow Rangers are 6/1 second favourites but, even if they are in the reckoning, Celtic have the pull and the finances to comfortably out-muscle Pedro Caixinha's side.
Whether the same applies to Championship sides South of the border remains to be seen, but realistically, how many chances is Wells going to get to play Champions League football? He might well consider a switch to Parkhead if an offer was to come his way.
