Striker Rickie Lambert has written a letter to Southampton fans thanking them for their support during his time at the club.
The Three Lions boss has largely rewarded Premier League form in a youthful-looking squad for the tournament in Brazil. See the full squad:
A disappointing afternoon for Southampton in their Premier League clash with Manchester City.
There was a certain air of relief when Guly do Prado, who spoke in the programme of his desire to win around Saints fans, slotted home a penalty midway through the first half - the Brazilian's first goal in two years and 11 days.
Jay Rodriguez and Adam Lallana saw efforts hit the woodwork either side of the spot-kick, but Yeovil were proving a handful it took for 18-year-old Sam Gallagher to open his senior account with a fine solo effort to put the game to bed and a smile back on Southampton fans' faces.
MP: “I spoke [with the chairman] for five minutes before the press conference. She transmitted her trust and support to me.” #saintsfc
MP: “I am fully committed to these players, to the staff and to these supporters. It would make no sense to leave this path.” #saintsfc
Doubts are now surrounding whether Mauricio Pochettino, Southampton's football manager, will remain at the club.
It's after Nicola Cortese resigned from his post as Chief Executive yesterday.
Katharina Liebherr has now taken on the role of non-executive chairman, with the search having begun for a new chief executive.
There are speculations that Cortese actually tendered his resignation in the autumn, with talks about the 45-year-old Italian considering his position back in May.
At that time, Pochettino warned he would leave Southampton if Cortese chose to do so.
In May, he said, "I would not understand staying in this role if Nicola was not here."
– Katharina Liebherr, Non-Executive Chairman
With great regret we have accepted the resignation of Mr Cortese. He has done a wonderful job at the club and we very much wanted him to stay. A search has now begun for a successor. In the meantime, it is business as usual and we will ensure that the manager, the team and all the staff at the club have all the help and support they need."
Southampton FC have confirmed the resignation of Executive Chairman Nicola Cortese, in a statement on the club's Twitter feed.
Owner Katharina Liebherr has taken on the role of non-executive chairman.
A statement on the club website says a search has begun for a Chief Executive Officer who will take over Mr Cortese's executive duties.
