The Tottenham and Sunderland stars are still on good terms, with the 33-year-old having left White Hart Lane in 2014.
With good reason. Defoe had just netted a hat-trick against Swansea City and was in a rich vein of form. If anyone was going to trouble Tottenham, it would be their former striker.
In the event, Sunderland couldn't quite continue their recent momentum and, as Sam Allardyce put it, his players 'failed miserably' during the last 20 minutes of their 4-1 defeat at White Hart Lane.
It's not too much of a disaster for the Black Cats. Spurs aren't their relegation rivals and a win in north London was never something Big Sam would have expected. It's something he could hope for, sure...
Despite seeing his side comfortably beaten, though, Defoe was pictured with former team-mate Hugo Lloris after the game. The Tottenham and Sunderland stars are clearly still on good terms and embraced warmly at full-time.
Next up for Spurs is a trip to Leicester City in the FA Cup, before visiting Crystal Palace in the Premier League. Sunderland, meanwhile, face a crunch clash against Bournemouth.
