Former Arsenal defender Martin Keown has hailed the impact of Ronald Koeman at Southampton.
Keown wrote in the Daily Mail: "Chelsea are top of the Premier League but it is Southampton who have impressed me most so far. Chelsea strengthened their squad; Southampton had the heart ripped out of theirs.
"As well as selling Adam Lallana, Dejan Lovren, Luke Shaw, Calum Chambers and Rickie Lambert, Southampton lost their chief executive Nicola Cortese and their manager Mauricio Pochettino.
"But they are once again punching above their weight - they sit fourth in the table before Saturday's tricky trip to Swansea - and their nightmare summer is fast becoming a distant memory.
"Their new signings have impressed me. Ronald Koeman is a bit of a journeyman, having been in charge with varying degrees of success at Valencia, Ajax, Benfica, PSV, Feyenoord, Vitesse and AZ Alkmaar but he is well respected and hugely knowledgeable."
