An early thunderbolt by James Maddison fired in from a tight angle after 37 minutes and a stoppage-time goal by the impressive Harvey Barnes sealed the points for a comfortable win.
The Saints dominated in the opening stages and created the first opening when Che Adams stretched the home defence on the counter-attack, while Leicester’s Barnes’ powerful drive forced Alex McCarthy into action with the game’s first shot after 19 minutes.
Leicester boss Brendan Rodgers: “I thought they started well. We didn’t counter-press. But then from 25 minutes we started to counterpress much better and we get the first goal from that, and it was a fantastic finish from James.”
“We’ve got lots of young English players and those playing for us today all impressed. I’m sure Gareth Southgate will be pleased with what he saw, especially in the second half.”
Southampton boss Ralph Hasenhuttl: “We gave our maximum against a strong side. We had more chances than them in the first half. It’s normal you take more risks as the game goes on and they had counter-attacks. We missed not only Danny [Ings], but at least one in every key area, so it was difficult for us, but the team was fighting well and this was a chance for the young lads to step in. This is the moment for them to step up.
“It’s never nice to lose a game but we had chances. We hit the bar, we fought with everything we have. We are definitely a team that is never giving up. The quality of the opponent was better than ours today.
