Polish journalist Tomasz Wlodarczyk has been left buzzing as Arsenal are set to sign Poland international centre-back Jakub Kiwior in a 'sensational' deal.

The Lowdown: Busy Gunners

The Gunners have certainly been busy over the last few days after missing out on the signing of Mykhaylo Mudryk to Chelsea, with Leandro Trossard set to sign from Brighton and Hove Albion and potentially even being able to feature against Manchester United on Sunday.

It now looks like they are going to make another signing very soon, after a recent update from Poland.

The Latest: Kiwior 'very close'

Taking to Twitter, Wlodarczyk has revealed that the North London club are also 'very close' to sealing what he calls a 'sensational' deal for Spezia central defender Kiwior:

"Sensational transfer very close to completion! Spezia and Arsenal are in very advanced talks about Jakub Kiwior. Jakub Kiwior will be one of the most expensive sold Polish footballers in history!"

Journalist Fabrizio Romano has added that contracts are already being signed for a fee in excess of €20m (£17.5m) plus add-ons on a five-year deal, with a medical to be completed 'in the next 48 hours'.

The Verdict: Gunners mean business

After the signing of Trossard, the Gunners have moved quickly onto securing another signing, showing that they mean business in terms of getting their hands on the Premier League title.

22-year-old Kiwior is very highly-rated, having been dubbed 'extraordinary' by his international team-mate Robert Lewandowski, while Polish football expert Ryan Hubbard thinks that he is a 'huge talent'.

Serie A analyst Matteo Bonetti has noted the 'impressive' season that he is having so far, as no Spezia player has averaged more interceptions, clearances or blocks per game in the Italian top flight than him (WhoScored).

Kiwior can cover at left-back and defensive midfield as well as at centre-back, and will provide healthy competition for Gabriel Magalhaes, who has played in every minute of the Premier League campaign so far.

Nonetheless, this looks to be another astute piece of business from Mikel Arteta and Edu.
