Whilst comparisons have been made between Ronald Koeman and Mauricio Pochettino throughout the season, nobody could have expected a war of words.
Pochettino guided Southampton to an eighth place finish last season, and his exploits on the South Coast earned him a move to Tottenham, replacing Tim Sherwood in the White Hart Lane hot seat.
His successor at St. Mary's Stadium was ex-Feyenoord boss Koeman, and he's recovered well from the losses of key players such as Calum Chambers, Dejan Lovren, Luke Shaw and Adam Lallana, with the Saints currently up in fourth place in the Premier League table.
Spurs sit just two points behind them, and Pochettino recently told Catalan radio station RAC1 that he laid the groundwork for Koeman's success.
Those controversial comments have sparked discussions between Spurs and Saints fans, and Koeman addressed the comments in a press conference today ahead of his side's trip to face Queens Park Rangers this weekend, as reported here by ITV.
"First of all, it was on Spanish radio so I don't know exactly what was said and if the comments were really like that," said the Dutchman. "He is free to give his opinions, I'm happy in Southampton and thank you Mauricio; I have an easy job!
"That is the reason that I came to Southampton, to have a little holiday with everything organised, a good team and good players. I'm joking! I have no comments," added Koeman, with an obvious hint of sarcasm in his response.
Given that Koeman had to come in and replace five key first team members in such a short space of time, get them playing impressive football and working together as a unit, it's ridiculous of Pochettino to suggest that Koeman's job is easier because of his own work.
But Pochettino did aid the development of players such as Morgan Schneiderlin, Victory Wanyama and James Ward-Prowse - players who feature prominently under Koeman.
