Big, big yes to Koeman. Famous former player and a really good manager. He is such a big name that he has more followers on Twitter than Everton official twitter has.
Koeman is doing an amazing job in Southampton. When he came there their squad was in shambles. He lost 4 best players and a great talent in his first transfer window. Replaced Lambert, Osvaldo, Ramirez, Lallana, Shaw, Lovren, Boruc and Chambers with Pelle, Long, Mane, Tadic, Bertrand, Alderweireld, Forster and Gardos. 4 more points and 13 goals better goal difference than they had under Pochettino. This year Saints have the same number of points as the last year already before the last match even through they currently have 6 goals worse goal difference. Koeman had to replace Alderweireld, Clyne, Schneiderlin, Cork, Mayuka and injured Forster and Gardos - he bought van Dijk, Soares + Martina, Clasie, Romeu, Juanmi (flop) - bought Austin instead of him and loaned in Caulker and Stekelenburg as injury backups. All of this when he has negative net spend of £22million. He brought Targett and Reed to the first team too, gave another few chances to few more youngsters too. That's the reason why I like him even over the likes of Mourinho.
Actually I hope he becomes our new manager. I would love to see one of the best ball playing defenders to teach a thing to John Stones. Would love to see him making our defence existant again - and actually quite good as well, his Soton team was one of the best defensive teams in the league while having a decent attack too.
I am in Koeman camp.
