#2 Lucas Perez
Spanish striker and Arsenal forward Lucas Perez is currently on loan to Deportivo La Coruna after failing to break into the Gunners first team last season. A possible candidate to leave the club permanently in January or at the end of the campaign, Perez has been disappointed with the number of chances he has been provided at Arsenal.
With Giroud a potential loss as well at the end of the season, Perez's exit could result in a situation where Wenger would be obliged to make a big money signing to replace the two players.
Whether Perez could be coaxed into staying at the club is uncertain, as the Spaniard wants consistent playing time which is not a guarantee at the club and could be out of London latest by the start of next season. However, Wenger will be careful with his sales as he will be desperate to win silverware and will use all the help he can get in what will be in his last year at the club.
