United hit their opponents on the counter and Lukaku had acres of space to run into down the right, before looking up and picking out Jesse Lingard, who controlled the ball and then tucked it out of Cech’s reach. The Gunners have progressed in seven of their last eight fourth-round ties, though, and they were right back in this contest when carving United open for the first time shortly before half time. Ramsey latched onto Iwobi’s pass on the overlap, held off Nemanja Matic and played the ball across goal for Pierre-Emerick Aubameyang to tap in at the back post. Jeered every time that he touched the ball in the first 31 minutes, Alexis Sanchez got his revenge by rounding Petr Cech and converting into an empty net from a tight angle to open the scoring. Romelu Lukaku claimed the assist after playing a disguised through-ball for Alexis, and the Belgian also played a direct part in the Red Devils’ second a couple of minutes later.
