He was taken off in the second half due to an injury.Ben White - 5/10Ben White gave his former team a chance from the spot with a poor challenge on Joe Gelhardt.Gabriel - 6/10Gabriel's namesake stole all the limelight with a brace while the Brazilian centre-back was totally anonymous.Kieran Tierney - 7.5/10Tierney was a real menace for Leeds all night with his overlapping runs.Thomas Partey - 7/10The Ghanaian made some good ball-recoveries in midfield.Granit Xhaka - 7.5/10Adventurous, inventive and industrious, Xhaka was a big threat to Leeds, even setting up Martinelli for his second goal. He was lucky to have escaped a booking for a nasty foul on Raphinha but saw a yellow for timewasting during a free-kick.Bukayo Saka - 8/10Saka missed an absolute sitter early on but played a big part in Arsenal's first goal of the night before getting on the scoresheet himself.Martin Odegaard - 8/10The Norwegian tested Leeds all night with a high press and released Smith Rowe for Arsenal's fourth.Gabriel Martinelli - 9/10The Brazilian was in inspired form last night, capping off an amazing performance with a brace.William Hill@WilliamHillGabriel Martinelli has been directly involved in a goal in five of his last six Premier League games:⚽️ vs Newcastle🅰️ vs Man Utd❌ vs Everton🅰️ vs Southampton⚽️ vs West Ham⚽️⚽️ vs LeedsGabi delivers the goods.11:32 AM · Dec 18, 202127241Gabriel Martinelli has been directly involved in a goal in five of his last six Premier League games:⚽️ vs Newcastle🅰️ vs Man Utd❌ vs Everton🅰️ vs Southampton⚽️ vs West Ham⚽️⚽️ vs LeedsGabi delivers the goods. https://t.co/hqxWOFQupMAlexandre Lacazette - 8/10The Frenchman was an excellent foil for his attacking cohort, pulling Leeds' defense apart with his movement to create space for others to run into.SubstitutesCedric Soares - 5/10Crysencio Summerville never gave him a moment's rest.Emile Smith Rowe - 7.5/10The run, the finish—both top-notch for his goal!
