Reigning Premier League champions Leicester City have whetted their supporters' appetites ahead of tonight's International Champions Cup clash against Barcelona by announcing their fifth summer signing. Highly-rated Poland international Bartosz Kapustka will join manager Claudio Ranieri and his new teammates in the Swedish capital of Stockholm after putting pen to paper on a five-year deal that will keep him at the King Power Stadium until 2021.

The 19-year-old winger's switch from Ekstraklasa outfit Cracovia to English football had been long touted, with Sky Sports reporting last week that Leicester had tabled an offer in the region of £5.25m ($6.99m). He has been handed the vacant number 14 shirt, last worn by former striker Martyn Waghorn two years ago.

"Leicester City Football Club are delighted to confirm the signing of Poland winger Bartosz Kapustka, subject to FA, Premier League and international clearance," the Foxes announced via a statement released on their official website.

Kapustka joined Cracovia from Tarnovia Tarnow in 2012 and appeared 60 times in total after making his first-team debut two years later. He has earned 11 senior international caps during his short professional career to date, catching the eye with four starts for quarter-finalists Poland at the European Championship in France . Adam Nawalka's side, who finished second in Group C, were eliminated by eventual champions Portugal 5-3 on penalties after a tight 1-1 draw at the Stade Velodrome in Marseille.

Leicester's fairytale rise from relegation fodder to a maiden top-flight title last term registered as one of the biggest shocks in British sporting history. Few expect them to retain their crown, with the likes of Manchester City, Manchester United and Chelsea all having installed top new managers, although they received a critical boost earlier this summer when irrepressible forward Jamie Vardy opted to resist overtures from Arsenal and instead sign a lucrative new four-year deal worth approximately £100,000-per-week.

They subsequently sold influential midfielder N'Golo Kante to Leicester for around £30m, but have so far managed to repel considerable interest in PFA Player of the Year Riyad Mahrez. Ranieri has already bolstered his squad for that upcoming title defence with the additions of club-record signing Ahmed Musa, Spanish defender Luis Hernandez, former Manchester United goalkeeper Ron-Robert Zieler and midfielder Nampalys Mendy.

After their clash with Barcelona, Leicester, beaten 4-0 by Paris Saint-Germain in California on Saturday (30 July), meet FA Cup holders United in the Community Shield at Wembley. They open the new Premier League campaign away to newly-promoted and managerless crisis club Hull City on 13 August before taking on Arsenal, Swansea City and Liverpool.
