And in another move that will help ease the hurt of seeing him sign for fierce rivals Southampton, he thanked Blues fans for their support during his season-long loan at Fratton Park from Manchester City.
But the opportunity to compete for a No1 spot in the Premier League proved irresistible after two loans season in League One.
And after making that leap of faith, he paid tribute to everyone at Pompey for helping him achieve that aim.
He told the Daily Echo: ‘Yeah, I know it’s a massive rivalry between two big clubs,
‘My time at Portsmouth was brilliant, I really enjoyed it and the fan base were brilliant.
‘They gave me a platform to go and play and without being there I wouldn’t have the opportunity to come here.
‘Now I’m looking forward to hopefully playing in the Premier League.’
The former Pompey fans’ favourite added: ‘To leave Manchester City was a big decision considering the size of the club and where they are, but it’s a brave and important one to make in my career.
‘I want to continue the game time I’ve been getting over the past two years and obviously I want to play.
‘The Premier League is the pinnacle, everybody wants to be here and like you said it doesn’t matter if I’m here but not playing as long as I’m here. I need to first of all prove that I’m ready to play, and if I get the opportunity I need to perform to keep my place.’
