Pompey fans were cursing Craig MacGillivray as they made their way out of Fratton Park back in January.
The keeper had pulled off several fine saves to ensure that Shrewsbury left the south coast with all three points.
But now he is hoping to ingratiate himself with those same supporters he was frustrating last season.
MacGillivray has penned a two-year deal with the Blues and is excited about getting started at his new side.
The 25-year-old said: “This is a massive club and now I’m looking forward to the beginning of pre-season.
“I can’t thank the gaffer enough for the faith he’s shown in me by bringing me here and it was a move I couldn’t really turn down.
“We played against Pompey when I was at Shrewsbury and the thing that really sticks in my mind is the noise and the sheer scale of the club. The fan-base here is huge.
“When I got the call asking me to sign here, that was all brought back for me and I just couldn’t wait to sign.
"The thing that really sticks in my mind is the noise and the sheer scale of the club."
“Hopefully the supporters will take to me and we can build a good relationship because I’ve come here to play games.
“My job is to keep the ball out of the net and so I’ll be looking to keep as many clean sheets as possible.
“The squad here is very strong for this level and so hopefully we can have a positive season that ends in promotion.”
MacGillivray is now looking forward to battling with Luke McGee for a place between in the sticks in the Pompey team.
He said: “I don’t want to come here and be a second choice, but Luke did well last year and there will be good competition.
“I’m going to work hard in pre-season and want to be in the starting line-up for that first match on August 4.
“At my age, I need to be playing regular games and be the number one, although 25 is still young for a goalkeeper.”
