Everyone is available, says the Englishman.
Leeds defender Gabriel Gudmundsson missed training on Tuesday and Wednesday due to illness, but participated in Friday's team training at the World Cup base in Dallas, USA.
"If he does well in training today, he should be able to play," Potter says of Gudmundsson.
Tunisia has the lowest world ranking of all the teams in Group F - the other two are the Netherlands and Japan - but Potter does not underestimate the North African national team.
"They are very strong defensively; they didn't concede a single goal in the qualifiers. They are very strong and compact and can also switch from compact to quick transitions. It's a good mix of young and old players, and we don't care too much about what other people think about different teams."
The hour has come.
Potter stressed to the world press several times that Sweden has the capacity to beat any team if all players do what they should and can.
And the opposite.
"If we don't play at our best and don't do what we should and can, every match will be difficult."
Three weeks after the first day of the World Cup gathering in Stockholm, the moment has almost arrived - the long-awaited World Cup premiere at the Monterrey Stadium.
Potter is ready, the team is ready. Now all the preparations boil down to 90 minutes of football.
"We have grown over time. The matches in Oslo and Stockholm (against Norway and Greece) were important; they showed what we needed to do. We have spent our time in Dallas well. We have been well looked after, had a good environment at a good training base."
Paying tribute to the visiting fans
"Now we're just looking forward to the match," says Potter, who doesn't intend to give a fiery speech.
Around 4,000 Swedish fans are expected for the premiere (04:00 on Monday). The support is important, both national coach Potter and team captain Victor Nilsson Lindelöf emphasize.
"The way I see it, the support has been incredible. The fans have been behind us the whole time; they were incredible against Ukraine and Poland," says Potter.
Nilsson Lindelöf is impressed by the number.
"The fact that they take their time and invest a lot of money in supporting us is not something we take for granted. We will do our utmost to take three points and make them happy," he says.
The team captain was asked at the press conference whether the opportunity to earn money from playing in a World Cup is a factor for the players.
"I could play a World Cup almost completely without compensation," says Nilsson Lindelöf.
