Southampton came out the stronger side and Tadic should have put the hosts in front inside four minutes, shooting wide from inside the six-yard area with the goal gaping.
The first chance of the second half came just a minute after the restart, when Tammy Abraham’s brilliant turn in the Southampton box gave him time to get a shot off, but his effort was blocked by Saints right back Cedric.
Pellegrini resisted the temptation to start with Mario Lemina, the striker signed from Juventus in a club record £18.1million deal earlier in the week.
Swansea were mired in a Premier League relegation fight for much of last season, with Clement’s arrival in January the turning point in their campaign.
Today’s opening game was Mauricio Pellegrino’s first competitive game in charge of Southampton.
“There have been times like that (thinking about retirement), I’m not going to lie”, Britton said ahead of Swansea’s Premier League opener at Southampton.
The Swans have failed to score in six of their 10 Premier League contests against Southampton.
Mauricio Pellegrino was nearly helpless as he stood at the sidelines and watched what was an incredibly frustrating afternoon for his side who failed to convert numerous efforts and can only hold themselves accountable for not opening their Premier League campaign with a win.
“There are times when you train hard, but if you’re not playing on the weekend it’s difficult”.
Southampton continued to pile on the pressure but could not find the back of the net and even with the introductions of Charlie Austin and Sofiane Boufal, Swansea managed to hold on and earn a precious away point that could be valuable when it comes to the end of the season.
“I’ve got this year with the option of another year, depending on how many games I play. We controlled the ball, created chances but this is football – you have to get goals and we couldn’t do so”, he said.
“Swansea is a good team, they were ready to attack us but we were well balanced and that was the key to controlling the game in the second half. I’m sure they will be disappointed and think “how have we not won”.
