The Southampton midfielder claims that Saints players were taken by surprise at Koeman's exit.
Southampton midfielder Oriol Romeu has told Mundo Deportivo that the club's players were taken by surprise by Ronald Koeman's departure from the club, and revealed that he only found out about his manager's exit through the players' group WhatsApp chat.
Koeman left St. Mary's earlier this month after two successful years to take over from Roberto Martinez at Everton, a decision which has left many at the south coast club reeling.
The Dutch boss appeared to be building a superb project at Southampton and led the club to finish sixth in the Premier League last season, their highest finish in 31 years.
However, his exit, along with the departure of star forward Sadio Mane to Liverpool, has left new Saints manager Claude Puel with a great deal of work to do this summer.
Though there had been much speculation as to whether Koeman would take the Goodison Park job, Romeu, who joined the club from Chelsea in a £5 million deal last summer, insists that the players were blindsided by his decision and also revealed the unorthodox way that he first found out.
The Spanish midfielder told Mundo Deportivo: "No one was expecting it in the dressing room. I found out through the WhatsApp group the players have.
"We were sorry to hear it because we got on really well with him and we were looking forward to doing something big in the Europa League."
Koeman's decision to leave the club is certainly one that rankles with many of a Southampton persuasion, including both supporters and those at the club.
That is not least because the Saints finished five places and 16 points above Everton and looked as though they had built a side which had every chance of becoming regular European challengers.
