Ronald Koeman cannot be accused of lacking persistency and after the arrival of Jordy Clasie he is looking to bring in another player linked last summer.
Latest central defender to be linked with Saints is QPR's Steven Caulker who was allegedly on Saints radar a year ago before moving to Loftus Road.
It was another bad move for Caulker who found himself relegated at the end of his first season at the club and it was deja vu as well as Caulker had suffered exactly the same fate after moving to Cardiff from Tottenham Hotspur a year earlier.
Now Saints are supposedly looking to finally bring Caulker to St Mary's, the media are saying that Ronald Koeman is attempting to take him initially on loan with the option to make the move permanent for a fee of around £8 million if he should impress.
Caulker at 23 has the right blend of youth & experience, although his appearances at Spurs were not that frequent, he played most of Swansea City's first season in the Premier in 2011/12 on loan before joining Cardiff in the summer of 2013 playing in every league game for them before following that up with his move to QPR last season where he only missed 3 Premier League games.
So undoubtably he ticks a lot of boxes and would make a good acquisition for Saints at that price.
Indeed if Koeman could bring Caulker in and even follow him with Virgil Van Dijk from Celtic the joint fee of around £20 million would make good sense and still leave Saints not having spent much more than the money brought in for Clyne & Schneiderlin.
That dual signing would be ideal providing competition in the centre of defence not to mention a potential replacement for Jose Fonte who will turn 32 in December.
A quality central defender is perhaps the last piece in Ronald Koeman's jigsaw, although a squad can always be improved, it is this area that Saints need to now put the piece in place and then they have time to look at what else needs improving going forward.
