#3 Flop: Danny Ings
After being an unused substitute during their 3-1 defeat by Manchester City to end 2018, Danny Ings should've come into this fixture with more verve, determination to succeed - particularly against the type of side that Southampton need his attacking influence against.
Instead, the 26-year-old struggled and was replaced by a more experienced Shane Long at half-time. The change didn't have any bearing on the full-time result and Long, 31, wasn't impressive either. But to his credit, he put himself about and did more than his attacking teammate's contributions in a sluggish first-half showing.
Ings has failed to score in all four meetings with Chelsea as a player, only West Ham (5) have eluded him more during his professional career. Hasenhuttl's still trying to establish his strongest - and most reliable - starting eleven, so performances like these aren't going to provide him with confidence that Ings is their number one option.
14 touches, 50% pass accuracy (lowest of any outfield player), caught offside once, dispossessed and fouled once, one shot - off-target - what more can be said?
