#3 Marcos Alonso exemplifies why Blues cannot afford any more injuries

In the simplest of terms, Lampard has not been helped by repeated injuries in his first season in charge at Stamford Bridge. Constant chopping and changing of his side has perhaps, not gone too well for his side's momentum.
He was forced to make a couple of changes even before half time. Emerson, who had just returned to the starting XI, was replaced by Alonso after a quarter of an hour. Further, Kurt Zouma came in for Andreas Christensen.
Now, time and time again, we've seen Alonso commit horrendous errors defensively. Chelsea should have learnt their lessons while knocking down set pieces, but alas, the Spaniard was again the guilty party.
Robertson played in a delightful cross but the sturdier Chelsea defense should have thwarted it all day long. Instead, Firmino's intelligence meant that he freed himself up in a pocket of space. Alonso stood watching while the Liverpool #9 broke ahead and netted a second.
