It won’t be long before the Gunners announce the arrival of another new player after completing and unveiling Leandro Trossard from Brighton on Friday.
Reports have it that the Gunners are closing in on the shock signing of Kiwior for €20m (£17.5m).
The Spezia centre-back is highly rated back in Italy and had a good World Cup campaign with Poland.
Poland’s captain Lewandowski is now singing the praises of the 22-year-old centre-back.
“The guy has great potential,” the Barcelona star told reporters about the defender.
“During the warm-up of the game with the Netherlands, I thought, ‘Who is this guy?’ Then, during the match, I realised that he is extraordinary.”
