Gavin Bazunu is certainly putting forward a case to be one of the Blues’ most successful loan signings.
The Republic of Ireland international – signed for the season from Manchester City – has impressed with his glovework on numerous occasions.
But the teenage stopper has also shone with the ball at his feet, often providing the starting point for Pompey’s attacks.
There was one shaky spell with a couple of errors against Rotherham and Ipswich, but Bazunu is not going to dwell on them.
He said: “You’ve got to put it behind you straight away and can’t let it affect your performance for the rest of the game.
“Afterwards you look at the videos, so you can recognise where you went wrong and try to improve on that.
“I’ve got a lot of trust in the way this manager does things here and am grateful for the trust that has in me.
"There’s absolutely no point dwelling on the past – you have to concentrate on the present and the next game."
“Part of the reason why you come out on loan in the first place is to learn from any mistakes that you make.
“There’s absolutely no point dwelling on the past – you have to concentrate on the present and the next game.
“To get to the top level, that’s the approach you need. You can’t afford to let one mistake become several.
“Those who put it behind them and go on to have a perfect game are showing why they play at an elite level.”
Bazunu will be aiming to help Pompey avoid slipping on an FA Cup banana skin when they host non-league Harrow this weekend.
He said: “Professionalism and concentration will be key – we have to approach the game in the way we would any other.
“There may be times when it’s pretty quiet for me, but I have to be ready because anything could happen.”
