After playing the role of a surprise package during the first half of the season and having risen like a phoenix from the flames, Southampton have grander designs in 2015 and have set their eyes on a European spot. Competing with their new found rivals financially is among their problems, but they are holding firmly to their key players. It could be a make or break window at St Mary's.
What they need
Only one team outside the top two have won more matches, scored or conceded more goals in the Premier League this season, so picking holes in this Southampton team is a tough ask. However, with Graziano Pelle having gone off the boil somewhat, a lethal forward is still required to cement the Saints' place in the top four shake up year in and year out. A pacey partner for Jose Fonte might also be required.
Who could join?
Netherlands international Elijero Elia is the first man through the door having joined on loan from Werder Bremen. The 27-year-old has already compared himself to current Southampton inhabitant Saido Mane - who will be at the African Cup of Nations this month. Wesley Sneijder has also been optimistically linked with a switch to the south coast but any other arrivals are likely to be reactive.
Who could leave?
The success or failure of Southampton's window activity potential lies in the future of Morgan Schneiderlin. The Frenchman was eventually convinced to remain at Southampton last summer, amid interest from Tottenham, but with the 25-year-old seeking a move to a Champions League club, Arsenal could prove too tempting a proposition. Despite having not played this season due to injury, Jay Rodriguez continues to be pursued by Spurs too.
What the manager has said
"We have already spoke about the transfer window," Koeman said. "We need one or two players in front because we don't have a lot of choices. We will lose Sadio in January as he will play in the Africa Cup of Nations.
"That means we will need good attacking players and we are looking for that and working on that."
