Terry has now scored for Chelsea in 17 successive Premier League seasons.
The Sky Sports pundit was full of praise for the Spain worldwide, who has played every minute of every league game this season, following Premier League champions Chelsea's 4-3 win over Watford on Monday night.
"I never wanted to hang about and stop the progress of a younger player - that was the basis of my decision". I have 12 days to make the best decision but in this moment I have 13, 14 players who want to play the FA Cup and there are many players in really good form.
John Terry opened the scoring after he was given his first Premier League start by Antonio Conte since September previous year, but it quickly turned sour for the club legend as his mistake allowed Watford to equalise through Etienne Capoue.
Michy Batshuayi, who scored the title-clinching goal at West Bromwich Albion on Friday, put Chelsea 3-1 up, but Daryl Janmaat pulled a goal back with a superb strike.
"It is a pity for me but I have to respect his decision because when you arrive at this moment, your heart, head and body tells you to continue because you want to continue to play and play regularly". I'm pleased for him, he scored a great goal.
Two minutes later Terry gifted Watford a rare away goal scored by Etienne Capoue, while he was also culpable in Stefano Okaka's strike which made it 3-3 before Cesc Fabregas' 88th-minute victor.
Terry has spent much of the season on the substitutes' bench as Italian coach Antonio Conte opted for a three-man defensive system that required more speed than the veteran has.
"It's amusing to see both teams score four and three at this stage of the season, but when you have won the league you can allow this type of situation".
Conte said: "I'm very angry with him, because he must think to share".
Win against Sunderland and Chelsea will become the first club to record 30 victories in a 38-game season and Conte could revert to his first-choice line-up after making nine changes against Watford.
With the result, the Blues move up to the 90-point mark at the top of the league table, with one game to go while Watford remain in 16th on 40 points. "Azpi played in a fantastic way", Conte added.
Sebastian Prodl was sent off for a second bookable offence in the second minute of stoppage time as Watford finished the contest with 10 men in a bad tempered conclusion.
"To me that team will take some beating". I'm still evaluating the team for next season. Subs: Stefano Okaka (for Niang, 71mins) 7, Troy Deeney (for Capoue, 90mins) 5. "There were some positives".
