Arsenal have reportedly lodged an opening bid of £22.5m for Saint-Etienne centre-back William Saliba.
Unai Emery is understood to have made the 18-year-old his number one transfer target this summer as he looks to bolster a backline which conceded 51 goals and kept only eight clean sheets in the Premier League last season.
The Gunners held talks with Saint-Etienne over a possible move earlier this week, and The Mirror reports that they have now made an official offer of £22.5m.
However, Saint-Etienne are thought to value Saliba at closer to £27m and are under no pressing need to lower that asking price considering that his contract does not expire until 2023.
The France Under-20 international enjoyed a breakthrough campaign in 2018-19, making 17 appearances as Saint-Etienne finished fourth in Ligue 1.body check tags ::
