The former Crystal Palace, Aston Villa and Middlesbrough star was already within the Three Lions setup when Sam Allardyce was forced to step down after just 67 days and one match in charge. Southgate took over on an interim basis, overseeing two wins and two draws before being handed the reins on a permanent basis in late November 2016.
After penning a four-year deal, Southgate had to wait until an away friendly in Germany four months later to name his first England senior squad after gaining experience as manager of the Under-21s. He would go on to oversee a 1-0 defeat in Dortmund as Lukas Podolski grabbed the only goal in what was the final game of his international career.
Several of the players called upon by Southgate with likely feature in the World Cup Finals in Qatar later this month - but the international careers of some others came to an end within months of that meeting with Germany.
1. GK: Joe Hart
The keeper spent time out on loan with the likes of Torino and West Ham United before severing his permanent ties with Manchester City to join Burnley in 2018. A one-season spell at Spurs offered little but Hart is now enjoying regular game-time with Celtic. Photo: Getty Images
2. CB: Chris Smalling
There was some surprise when Smalling left Manchester United to join Italian giants Roma on loan in 2019. Such was his success in Serie A, the move was made permanent and the defender went on to help Jose Mourinho’s side beome the first ever Europa Conference League winners. Photo: Getty Images
3. CB: Michael Keane
Keane remains at Everton after moving to Goodison Park in a reported £25m move in the summer of 2017. The summer arrivals of James Tarkowski and Conor Coady have limited his game-time this season. Photo: Getty Images
4. CB: Gary Cahill
Cahill’s seven-year stay at Chelsea came to an end in 2019 when he joined Crystal Palace. After remaining at Selhurst Park for two seasons, Cahill spent two years with Bournemouth but was released after their promotion into the Premier League last season. He remains without a club.
