Chris Sutton has admitted he is “concerned” about Celtic’s lack of business in the transfer window so far.

The Bhoys have made just one addition by bringing in Aberdeen ace Jonny Hayes, who is viewed as a direct replacement for loan star Patrick Roberts.

Brendan Rodgers is yet to make huge amendments to his squad and still has until 31 August to bolster his squad.

However, their Old Firm rivals Rangers have been very active so far and have already recruited eight new players as they look to improve drastically on their third-placed finish from last year.

Sutton has revealed his fear that Celtic have not added new faces in time for their crucial Champions League qualifiers in July.

“Rangers have not stood still but I’m slightly concerned at Celtic’s failure so far to move forward in the transfer market,” Sutton wrote in the Daily Record. “Patrick Roberts has left and Jonny Hayes has been brought in but that deal’s hardly earth shattering.

“The squad leave on Monday for Austria and the Champions League qualifiers are only a couple of weeks away. It makes sense for Celtic to bring in players now so they are settled and assimilated into the squad before these vital qualifying ties where a poor 20-minute spell can make or break a campaign.”

Celtic have a crucial two-legged Champions League qualifying match starting on 11 June, where they will face either Irish Premiership winners Linfield or San Marino side La Fiorita.

The Bhoys cruised to an unbeaten domestic treble last year, but performances in Europe were their only low point of the season.

Rodgers’ side made it to the group stages of the Champions League last year and will hope to at least make the knockout rounds of the elite competition this time around.
