Rio Ferdinand was not impressed with the performance of Timo Werner on Tuesday night, in Chelsea's 1-0 win over Atletico Madrid in the Champions League.
The Chelsea forward has scored 10 goals in 34 appearances this season in all competitions, and fans have been crying out for more from him.
'It's frustrating watching him, because you've seen clips of what he can do,' Ferdinand said on BT Sport, as Werner once again failed to get on the score sheet.
'It's not an easy chance, but you'd like to see him get it on target,' he said of one opportunity after the full time whistle.
