Southampton have lost two games in a row after a stunning start to the season, and manager Ronald Koeman may seek January additions to make sure the Saints maintain a top six spot.
A particular area where Southampton may need to strengthen is on the flanks, with competition for Dusan Tadic and Sadio Mane certainly needed.
With rumours of a bid for Twente's Jesus Corona, it seems clear that Koeman is pondering a move for a wide man - and now he could look to swoop on Arsenal.
The Gunners have the likes of Alexis Sanchez, Theo Walcott, Santi Cazorla and Alex Oxlade-Chamberlain, meaning that Joel Campbell has barely played.
The Costa Rican World Cup star has played just 38 minutes in the Premier League for Arsenal this season, and a January exit seems inevitable.
After loan deals with Lorient, Real Betis and Olympiacos, it seems that Arsenal are willing to loan the 22-year-old again, and according to the Daily Mail, Southampton looks like a realistic destination.
The likes of Calum Chambers, Oxlade-Chamberlain and Walcott could all recommend St. Mary's Stadium to Campbell having been so successful there themselves, but even so, it's the perfect move for Campbell.
Koeman needs depth behind Mane as a speed-based winger, whilst adding another left footer as cover for Tadic may also be needed - and Campbell fits both criteria.
The possibility of a permanent move also means that the Saints could get a great deal in signing Campbell, who could also play up front alongside Graziano Pelle having led the line for Costa Rica at the World Cup.
It's something of a surprise that Arsenal haven't used Campbell much so far this season, and the old adage of 'one man's trash being another man's treasure' fits the situation perfectly, with Campbell given the chance to shine in a young, vibrant team at Southampton.
