The Gunners added the Community Shield to their FA Cup success by beating a disjointed Manchester City side 3-0 at Wembley on Sunday.
The challenges which lie ahead over the next nine months will of course prove significantly tougher than those offered by Manuel Pellegrini's team, who had Willy Caballero in goal ahead of England's Joe Hart, several other regulars missing after World Cup duty and summer signings Bacary Sagna and Frank Lampard watching on from the stands.
Nevertheless, Flamini believes adding the likes of £30million Chile forward Alexis Sanchez, Mathieu Debuchy and promising young defender Calum Chambers show Arsenal now have the strength in depth to sustain a title challenge, which last season faded badly at the start of 2014.
"We have signed a few really good players, and that is excellent for us, because we have added a lot of quality to the team - we were already strong last season, but now we have added even more," Flamini said.
"Last season was good for us, even though we did collapse (in the league) over a couple of months.
"Now we are ready, with a strong team that has a lot of quality to be able to fight to the end."
Flamini added: "Of course this (win over Manchester City) will be good for the confidence to start the season, but we have to be focused because the season will be a long one, as you say here in England we must not forget that it is a marathon and not a sprint, so we have to make sure that we keep going until the end.
"But to win another title after the FA Cup is obviously very positive for us and shows that we are going in the right way.
"We have shown that we are very strong, now we have to be ready for the next game."
