The controversial talisman leading Chelsea's attack showed the worst side of his game against Liverpool in midweek, but it is a battle which Gabriel will not shy away from.
The photo above displays the Brazilian getting stuck into Diego Costa during a clash between Villareal at Atletico Madrid last year.
This was a game in November 2013 which Atletico did not manage to win, ending 1-1 with Costa failing to score, with Diego Simeone's side only netting via an own goal.
In the return game in April, Atletico won 1-0, but Diego Costa did not feature due to a hamstring injury.
What Arsenal have in Gabriel is a physical defender unafraid of clattering an opponent when he has to, and in many ways that has been what they have been missing at certain times.
Up against an opponent like Costa who likes to push defenders around and dominate up front, his previous experience of playing against the Chelsea striker could come in very useful.
