Three years ago, Hamilton was battling team-mate Nico Rosberg for the Drivers’ Championship which caused a heated feud as both drivers refused to speak to one another.
Rosberg beat Hamilton to the title and Bottas is in a strong position to follow suit this year.
The Finn secured pole position at the Spanish Grand Prix this afternoon as he looks to extend his one-point lead at the top of the standings.
And Wolff is worried that if Bottas continues to out-perform Hamilton it could cause a rift in the camp.
“A bit nervous is probably the right state of mind,” Wolff told Sky Sports F1.
“They know how important it is tomorrow to stay out ahead in Barcelona as it is a track where it is difficult to overtake.
“So I hope, I hope we will not be coming back to 2016.
“But these guys [Lewis and Valtteri] are in a totally different place with each other.
“We might have a little chat about that but they know exactly [what not to do].”
Hamilton was way off the pace as he finished over six-tenths behind Bottas in qualifying.
“It was an unfortunate session for Lewis because we couldn’t charge the battery properly after pitting in Q2,” Wolff added.
“So therefore his first run in Q3 was a bit compromised by the traffic.
“It started on the wrong foot [for Lewis] but Valtteri is good form and I guess deserves to be on pole.
“It could have even been the lower track temperature or you see in one of the corners there was a massive [amount of] gravel.
“You saw that the final sector was really down [on time] for everybody.”
