#2 Lucas Perez
Lucas Perez signed for Arsenal from Deportivo La Coruna in 2016 for £12.6m. Since joining Arsenal, he's played a total of 11 Premier League matches and scored once. However, his 3 goals in 3 matches in the Champions League for the Gunners was a redeeming feature for the Spaniard.
At the start of last season, though, Perez was sent out on a season-long loan to the club he signed from (Deportivo). He featured heavily for the Spanish side with 35 appearances, scoring eight goals and assisting six.
It doesn't take a genius to work out that Perez isn't a great fit for the Premier League, nor a side like Arsenal. Where he plays the best football is La Liga, so surely, for the sake of his career, it would be wiser to seek a move there before next season begins.
Where might Lucas Perez go?
As stated above, if Arsenal were to allow Lucas Perez to leave this summer, Deportivo La Coruna would be his ideal destination - simply because of the great relationship he's had with the club over the past few years.
However, Unai Emery would most likely aim to make a profit on the 29-year-old, so an offer would have to either meet his previous valuation of £12.6m or more.
