Celtic striker Leigh Griffiths has told the club's official Twitter account that their defending against Dukla Prague today was 'disappointing'.
The Bhoys were in pre-season action once again this afternoon, but fell to a 5-3 loss against Dukla Prague at St. Mirren Park, a stark contrast to the 2-0 win over Den Bosch in midweek.
Striker Griffiths got his name on the scoresheet from the penalty spot, but he couldn't save Ronny Deila's men from suffering a heavy defeat.
Griffiths spoke to Celtic's official Twitter account after the game, and whilst he appreciated the fitness aspect of the game, he admitted that he was disappointed with the performance from a defensive perspective.

Celtic started the game with Mikael Lustig, Dedryck Boyata, Charlie Mulgrew and Emilio Izaguirre in defence, which was certainly a patchwork backline considering it included a new signing in Boyata and a returning Mulgrew.
With a new arrival joining the backline, Celtic will take time to adjust and get used to each other, especially with right back Adam Matthews sold to Sunderland this week.
Conceding five against Dukla Prague certainly wasn't a good showing for Celtic, but with time and extra work on the training ground, that defence should be solid come the start of the season.
