The 36-year-old striker had yet to find the net in the first five matches for The Foxes, but during the visit to the port city, the 26-time international only needed 21 seconds to open the scoring. The captain put the visitors on the right track with an assist from Stephen Mavididi.
Then, Kasey McAteer doubled the lead for Leicester. Samuel Edozie brought hope back into the hearts of The Saints' fans shortly after, but Wilfred Ndidi dashed that hope again before half-time. The final act at St. Mary's Stadium came in the second half with Mavididi. Kamaldeen Sulemana, previously linked to Ajax, was sent off with a red card in the dying moments.
Leicester City has accumulated fifteen points in the Championship after six matches. They suffered a 0-1 defeat to Hull City just before the international break. Southampton, with ten points, lags slightly behind the leaders, occupying the seventh spot in England's second tier.
