Southampton manager Ronald Koeman has told the Daily Echo that he is 'working on' making more new signings having brought in defender Steven Caulker on Wednesday.
Following the potentially season-ending injury to Florin Gardos last week, Southampton needed a new centre back, and former Tottenham youngster Caulker has arrived on a season-long loan having suffered relegation with Queens Park Rangers last term.
Caulker joins the likes of Maarten Stekelenburg, Cuco Martina, Cedric Soares, Jordy Clasie and Juanmi at St. Mary's Stadium, with Koeman again having to rebuild his squad, just as he did last summer.
Nathaniel Clyne and Morgan Schneiderlin have been replaced following their moves to Liverpool and Manchester United respectively, but fans are still keen to see another centre back arrive having lost loan defender Toby Alderweireld to Tottenham.
"I think still we need some players more to have really competition in our squad," said Koeman. "We are working on it and sometimes you need a little bit more time We are not in a hurry because we like to have the players what we like to have in the team and sometimes you need more time for that," he added.
Supporters will want to see another defender, as well as a centre forward to help ease some of the goalscoring burden on Graziano Pelle - with Charlie Austin arguably an ideal signing for the Saints after 18 goals for Queens Park Rangers last season.
Loan winger Eljero Elia returned to Werder Bremen earlier this summer, so another wide man could be targeted, with Southampton's squad not yet complete.
