The former Southampton player took aim at Koeman on Twitter
On Tuesday, it was announced that Everton had found the man they wanted to replace Roberto Martinez in the form of Ronald Koeman.
Having played under Koeman at Southampton before moving to Bournemouth, the Polish goalkeeper took to Twitter to share his feelings on the matter once the move was confirmed by Everton.
Boruc doesn't seem to be a huge fan of the Dutchman, as he posted an image of him with a falsely attributed quote about loyalty and not moving simply for money.
That message garnered thousands of retweets, which drew another response out of the former Celtic player, who was a bit more cryptic this time around.
