With a win over Newcastle United this weekend, Southampton confirmed their status as genuine top-four contenders this season.
Many had felt that the Saints would fall away, but their prolonged challenge for a spot in Europe's premier competition has lasted the distance and there can be no doubting their credentials now.
There have been a number of reasons for Southampton's good form this season, but arguably the main factor has been their impressive recruitment.
Ronald Koeman has brought in 10 players during his time at St. Mary's and only one new arrival has not had the desired impact.
It is a quite remarkable success rate and in this piece we take a look at all of the side's transfer business.
Dusan Tadic (FC Twente)
The Serbian has made a brilliant start to Premier League life. He already looks one of the brightest talents in England and his performances have made him a stand-out player for Southampton this season. Tadic has claimed three goals and seven assists since joining the South Coast club and he looks a player they can build their team around for years to come.
Graziano Pelle (Feyenoord)
The Italian striker has seamlessly filled the void that Rickie Lambert left, showing his ability. With an eye for goal, Pelle has added a presence to the Saints' front-line and he is also deadly when given a chance.
Ryan Bertrand (Chelsea) - Loan
Considering the vast amount of money Manchester United signed Luke Shaw for, Bertrand had a lot of pressure to show he was as good as his predecessor. However, he has immediately impressed and already there is talk about his chances of getting back in the England squad. The youngster has pace, power and discipline and he has played a big part.
Saphir Taider (Inter Milan) - Loan
The one unsuccessful transfer of Koeman's reign. Taider joined this summer and was expected to be the creative fulcrum of the side, but he ended up returning to Inter in rapid fashion.
Fraser Forster (Celtic)
The goalkeeper has impressed at St. Mary's so far, helping Southampton's defensive record be the best in the league. Forster has kept 11 clean sheets in a Saints shirt to date.
Shane Long (Hull City)
Although his scoring record may not be the most flattering, it would be wrong to gauge Long's contribution through the amount of goals he scores. The Republic of Ireland international offers far more to the side than just goals and his effort and work-rate is unquestionable.
Florin Gardos (Steaua Bucharest)
Used as cover so far, Gardos has proven a capable deputy when called upon.
Toby Alderweireld (Atletico Madrid) - Loan
One of the highest profile signings Southampton have made, Alderweireld has not disappointed. Composed and commanding, he looks a brilliant addition.
Sadio Mane (Red Bull Salzburg)
The rapid winger has caused defences up and down the league problems because of his natural attacking instincts. Although Mane is still raw, he has the potential to be a huge star for the side.
Eljero Elia (Werder Bremen) - Loan
The Dutchman's arrival was questioned at first, but he has already shown his worth to the side. Elia can be a controversial character, but he looks like a player with a point to prove and his two-goal display against Newcastle United at the weekend is sure to have endeared himself to fans of the club.
