The 6ft 7 England goalkeeper completed his £10 million switch to Southampton yesterday after four seasons playing in the SPL for Celtic.
It is a return to England for Forster who started his career out at Newcastle United, and the shotstopper says the time was right for him to come back.
In his first Saints interview, he said: "I just felt it was a fantastic opportunity. Southampton is a top club and they're playing Premier League football every season at the minute.
"It was an opportunity too good to miss and I'm just delighted to be part of it now."
During his time at Celtic, Forster won the Scottish title three times, the Scottish Cup twice and also featured on the biggest club stage, the Champions League.
And the 26-year-old reflects well on his time at Celtic Park: "I've had a fantastic time at Celtic. I have loved every minute, it's a special club and I am proud to have played for them.
"But I just felt now was the time for something new and a new challenge. To go and play in the Premier League for a club like Southampton is something special and something I'm really looking forward to being part of."
It's quite common knowledge that this summer has been pretty disastrous for Southampton. Despite the likes of Lambert, Lallana, Shaw, Lovren and Chambers all departing for bigger clubs, Forster says he didn't need too much convincing to sign.
"They didn't have to say to much to me, it's a moment of transition for the club but there are still so many positives. There is still very good players here and it's a very good club.
"A lot of clubs have these moments where they have to sell players and bring the next batch through, so I'm just delighted to be here and for the club to have put their faith in me."
The England international also spoke very highly of the new Southampton manager Ronald Koeman, saying the opportunity to play under the Dutchman is a once in a lifetime thing, and one he wasn't going to pass up.
Despite being a highly rated English keeper Forster has never played in the Premier League. He was at Newcastle for six years but did not play a single competitive fixture before being spending loan spells at Stockport County, Bristol Rovers and Norwich City.
Should he start, then Forster's debut will in Southampton's first game of the season away at Liverpool this Sunday, and he says it is something he is much looking forward to.
"It's a brilliant game to have first up and obviously it's very tough and they've spent quite a bit in the transfer window.
"But to go and play at Anfield is something special and it's important we do everything we can this week on the training pitch.
"There might be some ex-Southampton boys playing against us but it's important we focus on the football and go out and give everything we can."
