As 2014 draws to a close, we take a look at Southampton's worst moments from the last 12 months.
The Argentine, 42, won just over 38% of his games in charge of the Saints, earning plaudits for the superb brand of football on show at St. Mary's Stadium - and his departure was a huge blow to a developing Saints side.
Departures; lots of them: Shortly after Pochettino's exit, Southampton had to deal with a host of other losses, including Adam Lallana (above).
Lallana moved to Liverpool alongside Southampton team mates Dejan Lovren and Rickie Lambert, whilst Calum Chambers left for Arsenal and Luke Shaw moved on to Manchester United - bringing in almost £100m to the Saints, but losing a number of superb players.
Four defeats in a row: it's mostly been a year of highs for Southampton, so it's hard to pick a true down time for manager Ronald Koeman, but the 1-0 defeat to Burnley was something of a low.
The newly promoted Clarets snatched a 1-0 win over the Saints, meaning they had lost four games in a row, bringing an end to the superb start for Southampton.
Dusan Tadic missed a penalty and looked visibly disappointed, but Southampton have recovered since, with 2015 looking bright for Koeman's men.
