Nevertheless, Arsenal remain favourites to finish top of the pile, which carries its own pressure, but Campbell knows a thing or two about meeting expectation after helping the Greek giants to league success during an impressive loan-spell in 2014.
Although Campbell acknowledges the difference between both countries' divisions, the Costa Rican believes that handling pressure is a universal quality.
“We have many chances with this team but it is a very tight fight at the top of the table,” he told Arsenal's official website. “We are just focused on our work, go from match to match and we hope to become champions.
“I don’t know [how important my Olympiacos experience can be]. Greece is a different competition from the Premier League
“Olympiacos were the team to beat in Greece, so in every match we had to go out to win it. Arsenal is a candidate for the title here and we have to win every game too, that pressure is always there. But we are Arsenal, we are a big team and we are used to it.”
The North Londoners have failed to win the Premier League since the Invincibles did so without losing a game during the 2003-04 season.
Should they end that hoodoo, it could form the first part of a domestic double as Wenger's side remain in contention for a third successive FA Cup crown.
Arsenal are also still in the Champions League, though their hopes of reaching the quarter-finals hang by a thread following a 2-0 first-leg home defeat by Barcelona this week.
