Southampton defeated a shambolic Chelsea 2-1 thanks to a first-half comeback.
It was Sterling who first opened the scoring with a close-range tap-in, but Lavia equalized just five minutes later.
In the first-half stoppage time however, Armstrong scored the decisive goal that handed them the victory.
Southampton continued their excellent play into the second half, and they could have added a third if Silva hadn’t made a brilliant goal-line clearance to deny Salisu.
By and large, the saints are back on track, and the three points they secured tonight lift them above Chelsea into seventh place while they prepare to face Wolves.
Truthlive.net correspondent who monitored the match noted that Chelsea couldn’t find their rhythm today, and Tuchel will be hoping they can rebound against West Ham on Saturday.
