Saints host Tottenham Hotspur with the unusual kick-off time of 7pm, due to the visitors having played in the UEFA Europa League on Thursday evening.
TNT selected the match for TV broadcasting but cannot air games in the usual 2pm and 4:30pm Sunday slots reserved for Sky Sports fixtures.
TNT Sports have confirmed the 26 year old will be a guest on their coverage of the match, offering insight on his teammates and former Arsenal rivals.

Saints goalkeeper Ramsdale has been ruled out of the fixture but he is nearing a return from surgery on a broken finger over a month ago.
Ramsdale will line up alongside Joe Cole and former Saint Peter Crouch, with Lynsey Hipgrave on presenting duties from St Mary's Stadium.
TNT's coverage of the Saints match starts at 6pm on Sunday, December 15, with both managers involved under increasing pressure from media and fans.
England international Ramsdale has made nine Premier League appearances for Saints since signing from Arsenal in a deal worth up to £25million.
Ramsdale signed a four-year deal at Staplewood in August and kept his first clean sheet for the club in a 1-0 win over Everton at the start of November.
