Since moving to the south coast from Scottish side Rangers, he has been a household name within the St Mary's faithful and has been a big part in this resurging Saints side.
Start of a Sainthood
He made an immediate impact in his debut. Saints were away to reigning champions Manchester City and he netted in an agonising defeat to the champions on the opening day of the 2012/2013 season. Which turned out to be an impressive season for Davis and Saints.
Under Nigel Adkins he was a regular starter in the side but after he was sacked and replaced by Mauricio Pochettino, Davis had to settle for more time on the bench under his reign.
Finally the Northern Ireland captain earned himself a start under Pochettino, and yet again it was against the champions Manchester City. Davis delivered again and scored in a 3-1 victory at St Mary’s.
After that impact, he found himself back as a regular in the side for not just the rest of the season, but the following season also. Saints surviving for back to back seasons after their return to the top flight.
Every cloud has a silver lining
Sadly, Pochettino vacated for a job with Europa League rivals Tottenham Hotspur, which seemed to be a blessing in disguise for Davis. In came Ronald Koeman, and this was instrumental in his success and nailing down his position in the starting 11.
His importance to the team was rewarded, after he was given a contract extension keeping him at the club until 2018 and being named vice captain behind Jose Fonte, after saints recorded their highest ever Premier League points tally.
This season has been a terrific one for the midfielder, only missing three games all season and netting four so far, even one in the historic 3-1 win at Chelsea earlier on in this season.
Davis has been in top form this season and hopes to continue it into the European Championships this summer. His Northern Ireland side face World Champions Germany, Poland and Ukraine in France, and plan to ruffle a few feathers.
