Everton boss David Moyes has admitted he was shocked by Friday's sacking of Nigel Adkins at Southampton.
Moyes' men travel to St Mary's on Monday in what will be Mauricio Pochettino's first game in charge of the Saints.
The Argentinian was immediately installed after Adkins was shown the door, despite the manager having taken Southampton to successive promotions and 15th in the Premier League table.
Moyes said: "I'm very surprised. I was talking to my staff during the week and complimenting how well Nigel Adkins had done. It was always going to be difficult after two promotions. Anybody who does that coming up, it's a long way up.
"He'd just got himself out of the bottom three and moved up and I don't think there would have been many people looking at Nigel Adkins to be sacked in that position."
Moyes celebrates 11 years in charge at Goodison Park this year and he said the trust shown in him by chairman Bill Kenwright and the board is an increasingly rare commodity in football....
