William Saliba is "ready" to make a significant impact for Mikel Arteta and Arsenal, believes Saint-Etienne manager Claude Puel. 

Arsenal signed the highly-rated 19-year-old in a £27million deal last summer, with the defender returning to the French club on loan for the 2019-20 campaign. 

The youngster has already played his last game for the French side however, with Ligue 1 concluding prematurely back in April, Saliba playing just 15 games for the French club this season due to a three-month injury lay-off.
