(CNN) -- Montpellier's France international striker Olivier Giroud has agreed to join English Premier League club Arsenal. Giroud, who passed a medical at Arsenal's training ground on Monday, was a key player for Montpellier last season as the French club won Ligue 1 for the first time in their history, scoring 21 goals in 36 appearances. The 25-year-old, who made three substitute appearances for France during Euro 2012, will officially join Arsenal on July 1 on a "long-term" contract though Arsenal did not disclose the length of the deal. Italy reach semifinals after penalty-shootout triumph "We're delighted to have secured the signing of Olivier Giroud," Arsenal manager Arsene Wenger told the club's website.
