Pompey have spent the summer being linked with a host of top names including Peter Crouch, Shaun Wright-Phillips, Younes Kaboul, Richard Dunne and Eidur Gudjohnsen.

Yet so far, only out-of-contract Glen Little and on-loan Ben Sahar have arrived at Fratton Park.

The apparent lack of transfer activity has sparked concern among some quarters – with pre-season training starting on Tuesday.

Storrie, though, remains confident the additional top-quality signings Harry Redknapp craves will materialise.

The Blues are believed to be ready to up their bid to land Crouch from Liverpool.

And after a Premier League transfer lull which has seen hardly any deals completed so far this summer, Pompey chief executive urged fans not to panic over other signings.

He said: 'I can assure supporters we will strengthen the squad with quality signings over the summer – it's just at the moment it is a naturally quiet time.

'Everyone is away having their holidays and that goes for players, managers and, of course, chief executives.

'This is also a summer in which there's been a tournament taking place, which also delays matters.

'There is no need to panic – not much will happen until the middle of July.

'We know what we want. It has been discussed between myself and Harry, and it's now about waiting for those targets to become available and taking it from there.

'Of course more players will be arriving. But we have no deadlines to sign anyone.

'We know what we want and we are focusing on them. There's definitely no need to panic.'

Harry Redknapp has made no secret of his desire to strengthen the striking department with Crouch remaining the prime target, despite having a £9m bid turned down.

He is also keen on Kaboul, the Spurs defender also fancying the switch to the south coast, although both clubs have yet to agree a fee.

Pompey are after a left- back with Nicky Shorey and Wayne Bridge the names cropping up.

And Wright-Phillips continues to be linked, with Redknapp keen to turn his attentions on the Chelsea winger after long-time target Jonas Gutierrez signed for Newcastle.

Meanwhile, Kanu has reiterated his desire to sign a new deal at Pompey.

He said: 'There are just some little details that we need to discuss. But I will sign the contract.'
