The former Blues midfielder says the club should have backed Frank Lampard by bringing in reinforcements during the winter window
Former Chelsea star Joe Cole has criticised the club's decision not to buy during the January transfer window following the Blues' 3-0 defeat at the hands of Bayern Munich on Tuesday.
Serge Gnabry scored twice and Robert Lewandowski added a goal of his own as Chelsea were undone at Stamford Bridge.
The loss comes on the heels of a quiet January, as Chelsea failed to bring in any new signings despite seeing the club's FIFA-imposed transfer ban halved on appeal.
