Artur Boruc will sign for Fiorentina, according to the Italian club. The Celtic goalkeeper is reported by the Italian press to have agreed a two-year contract with the Viola, with the Hoops receiving £1.7 million for his services.

After months of speculation over the Polish player's future, things moved quickly on Monday after talk of Fiorentina's interest intensified over the weekend. Boruc was in the Celtic party which flew from Glasgow to London early on Monday morning but rumours began to circulate during the afternoon he had been withdrawn from the team's connecting flight to Philadelphia at the last minute.

Hours later, it became clear the goalkeeper was on his way to Italy for a medical instead of travelling onwards with his team-mates, who are bound for the USA to take part in four pre-season games.

Various sources in Italy revealed on Monday evening the keeper would arrive to provide competition to French keeper Sebastien Frey, who has been persistently linked with a move away from Fiorentina this summer.

Those reports were then confirmed by Fiorentina's official website shortly after 6pm, the Serie A club saying in a short statement they had agreed to sign Boruc, pending a medical. It read: "ACF Fiorentina can announce they have reached an agreement with Celtic for the acquisition of Artur Boruc. The negotiations will be formalised after the results of a medical."

Boruc, 30, moved to Scotland in 2005 from Polish club Legia Warsaw, quickly establishing himself as a fans' favourite at Celtic Park. However, with just one year left to run on his contract with the SPL club, speculation had been rife he would be sold this summer, to avoid Celtic losing the player on a free at the end of the season.

He leaves Scotland having made 220 appearances for Celtic in five years, during which he won three SPL titles, two League Cups and one Scottish Cup winner's medal.

Lukasz Zaluska, Boruc's compatriot, will take over the gloves for Celtic's four games in America, where they will play Philadelphia Union, Manchester United, Seattle Sounders and Sporting Lisbon. American keeper Dominic Cervi may also get the chance to impress new boss Neil Lennon, having found his opportunities limited since his move from Michigan Bucks in 2008.

Boruc's arrival in Florence will increase speculation over the future of current Fiorentina keeper Frey, who has most recently linked with a move to Aston Villa. Frey, who was capped just two times for France before he retired from international duty in 2008, has spent five years with the Viola and has spent the majority of his career in Italy, having also had spells with Internazionale, Verona and Parma.
