LONDON -- Antonio Conte claimed that Chelsea had made a "big psychological step" after a 4-2 win over Southampton at Stamford Bridge moved the Blues seven points clear of Tottenham at the top of the Premier League on Tuesday.
Goals from Eden Hazard, Gary Cahill and a second-half double from Diego Costa earned Conte's men a hard-fought win against a confident and dangerous Saints side, who twice found a way past Thibaut Courtois courtesy of former Chelsea men Oriol Romeu and Ryan Bertrand.
