Celtic recently signed Moussa Dembele in the summer transfer window.
The Scottish Premiership champions have made just one signing so far in the summer transfer window.
The Bhoys have recruited 19-year-old forward Moussa Dembele, who was one of the best young players in the Championship last season.
Kristoffer Ajer has also joined Celtic this summer, although the 18-year-old midfielder had agreed the move back in February.
With Champions League qualifiers set to start soon, the Bhoys do need to sign players in order to enhance their chances of progressing to the group stage of Europe’s premier club competition next season.
According to The Daily Mail, Celtic manager Rodgers is looking to sign a defender this summer.
The former Liverpool and Swansea City boss has suggested that there could be an update on the situation by Wednesday.
“Absolutely nothing,” Rodgers told The Daily Mail when asked for a transfer update. ’Not yet. Hopefully, we’ll see by Wednesday.”
Celtic’s main aim at the moment is to qualify for the group stage of the 2016-17 Champions League campaign.
The Bhoys will start the new season as favourites to win the Scottish Premiership title, although Old Firm rivals Rangers will be expected to give them a run for their money.
