Sánchez scored the first goal in Arsenal's 2–1 home win over Queens Park Rangers on 26 December and assisted the second goal for Tomáš Rosický; earlier in the same match, Sánchez had a penalty saved by goalkeeper Robert Green after being brought down by Armand Traoré. On 4 January 2015, Sánchez scored and assisted his first ever FA Cup goals as Arsenal knocked out Hull City, the previous season's runners-up in the third round. Sánchez assisted Per Mertesacker and scored in the 82nd minute, being substituted two minutes later by Chuba Akpom. In Arsenal's next Premier League match, against Stoke City, Sánchez was involved in all the three goals as Arsenal beat "the Potters" 3–0 at the Emirates. He first assisted Laurent Koscielny and then scored two goals of his own. His performance was praised by Thierry Henry, who called him, "Arsenal's best signing of the last six years."
