The fans favourite returned for his second stint at Roots Hall on a permanent basis this afternoon after signing a two-year deal.
And Eastwood, who scored 65 goals in 135 games during three memorable seasons at Roots Hall, wants the good times to follow once more.
"It was never really in doubt that I would come here," Eastwood told the official website today.
"I came back at the end of last season and really enjoyed it and I am happy to come back permanently now.
"Being at Southend is the most enjoyable time I have had in my career and that is what has brought me back here twice.
"It took a while to get everything done but I am back training and that is going well so I am delighted to get pen to paper."
The former Wolves forward spent the end of last season on loan from Coventry City as Southend pushed for promotion.
The 28-year-old made nine appearances scoring twice but struggled with a knee problem.
But after a minor operation this summer Eastwood is tipping himself to rediscover his previous heights.
"I know I will score goals if I stay in the team so getting fit and selected has to be my first aim," he said.
"If I am in that starting eleven I will be up there with the top goalscorers this season.
"The one good thing we can take from last season is the experience.
"We now know what it takes to get there and the feeling of not getting promoted so if we are in the same situation next year we can try that little bit harder and get over the line."
And despite dropping two divisions to rejoin up with the Blues the Welsh international striker had no qualms about the move.
Freddy admitted: "The manager and the players he is signing want to push on to the next level and I think we can.
"This squad of players feels a bit like I have been here all the time.
"Pre-season is hard work but it is good to be back around everyone, there's a good spirit in the squad.
"The first week has been tough but we've got our first game this weekend and that's when it starts to get more enjoyable."
