Obviously, Rodri won't start on Sunday after having played full games vs Dortmund, Chelsea and Villa.
If Kevin is fully fit, he will probably start in order to get 60 minutes under his belt before PSG.
None of the midfielders and attackers who are going to start vs PSG won't play more than 60-70 minutes. Same with Dias.
Pep can make 5 changes, and he will use them to make sure that virtually any of the starters in Paris will play no more than 60-70 minutes vs Spurs (including extra time).
That is, Pep is likely to make at least 5-6 changes, but 7-8 are more likely. The biggest conundrum is to find partners for Dinho in midfield. Can be solved in two ways: either start KDB and Bernardo and then sub them off for Gundy and Foden, so that none of them plays more than 60-70 minutes (with extra time), or use 3 in defence and put Cancelo and Mendy next to Dinho plus one out of KDB/Bernardo/Gundy/Foden.
Most probable line-up:
SteffEn
Cancelo
Ake/Dias
Laporte
Mendy
Dinho
KDB/Gundy
Bernardo/Foden
Torres
Jesus
Sterling
Or:
SteffEn
Dias/Garcia
Laporte
Ake
Cancelo
Mendy
Dinho
KDB/Bernardo/Gundy/Foden
Torres
Jesus
Sterling
