Nathan Redmond says there has been a noticeable buzz around the training ground since the end of the international break, as the team embarks on a huge week.
Saints return to Premier League action this Sunday, as they host Burnley, before they travel to Milan for a Europa League clash with Internazionale then return to England for a visit to Manchester City.
"I think Thursday summed it up, with the buzz around the training ground,” said Redmond.
“Everyone was excited to see each other and get back to work and that showed on the training pitch and will hopefully lead into the game on Sunday.”
Redmond himself returned from international duty on a high, having helped England Under-21s qualify for the EURO 2017 finals, with wins in Kazakhstan and then at home to Bosnia & Herzegovina.
"It was a proud moment again, to obviously get called up, but to then finish up qualifying for the finals next summer,” he said.
“After the first game, it was sort of job done, and then the second game was just about finishing off in style. Myself, Prowsey and Jack Stephens, who went away on this trip, we're all proud that we've come back with a successful campaign under our belts.
"I went into the international break coming off the back of a good run here at Southampton, and to go away, winning another two games, we're on that winning high at the moment, so I've come back in good spirits and am ready to work hard again.”
