Worried Kris Commons has called for Celtic to bolster their defensive ranks for a charge on the Champions League after the lacklustre showing against Rangers.
The Scottish Premiership champions struggled to get to grips with Michael Beale's side at Ibrox as the Light Blues dominated derby day to secure the Londoner's first win since stepping into the hot seat in Govan. The result has put Celtic hero Commons on red alert for next season - as he admits he has growing concerns over the European goals of the Hoops when they go into the group stage.
Carl Starfelt, Alexandro Bernabei and Yuki Kobayashi sparked fears after they failed to keep tabs on the likes of Fashion Sakala, Todd Cantwell and John Souttar at key points against Rangers - and Commons reckons Celtic will need better summer recruits to compete with Europe's elite. Commons pinpointed problems with Starfelt's display without Cameron Carter-Vickers in defence - and admitted that another first-choice centre-back.
