Update on Portsmouth's pursuit of Leicester centre-back Josh Knight

It is understood the Premier League outfit are aware that the Blues are keen on the centre-back.

Championship sides are also believed to be admirers of Knight, though, which could go against Kenny Jackett's side after they failed to be promoted via the League One play-offs last month.

However, the second-tier clubs wanted to see more of the 22-year-old featuring in defence during his loan spell at Peterborough rather than in midfield.

That, therefore, goes to Pompey's advantage as they look to strengthen their options at the back.

Knight spent the past one-and-a-half season at the Posh.

Last campaign, he scored three goals in 23 outings – but the majority of those were in a central-midfield role rather than in the rearguard.

Knight has a year remaining on his deal at Leicester and has made only one first-team appearance.

The caveat to bringing in the Fleckney-born man is that he'd count towards a squad cap of 22 senior players which could be implemented for next season when League One clubs vote on Thursday.

If the Blues are looking to sign a centre-half on loan, they may be tempted by someone below the age of 21 who wouldn't count towards the wage ceiling.

As things stands, Pompey currently have just two senior central defenders under contract.

As reported by The News, the Blues are closing in on an agreement that will see Sean Raggett return to the club following his loan spell from Norwich last season.

He scored two goals in 38 appearances and is available on a free transfer after being released by the Canaries.

However, the Blues still need to find a replacement for Christian Burgess following his departure to Belgian side Royale Union Saint-Gilloise.

Meanwhile, Paul Downing is looking to fight his way into Jackett's plans after a frustrating maiden season on the south coast.

The ex-Blackburn defender made just 14 appearances last term and didn't feature in the league after September 17.

However, Downing will be aiming to showcase his attributes when Pompey return to pre-season training tomorrow.

Jack Whatmough will also be gunning to win back a starting spot after an injury-hit campaign.

The academy graduate has now recovered from the third serious knee injury of his career.

He made two appearances before the curtailment of the previous campaign.
