On 30 November 2016, Martial was recalled to the side to face West Ham in the EFL Cup after receiving warnings about his starting spot in previous weeks from manager José Mourinho, he responded by scoring two goals in a 4–1 win to send United into the semi-final of the competition. Being in and out of the team for a couple of months, Martial was rumoured to leave Manchester United in the summer, but on 6 February he made it clear on his official Twitter account, tweeting: "the paper's are wrong don't listen to them". Martial returned to the starting line-up against Watford at Old Trafford on 11 February by providing an assist to Juan Mata and later scoring a goal for himself in the 60th minute, he was later declared the man of the match. On 26 February, he was named in the starting XI that faced Southampton at Wembley Stadium for the 2017 EFL Cup Final, which United won 3–2. The victory earned Martial his third piece of silverware for United. In May, he won the first European trophy of his career, coming on as a substitute in the 2017 UEFA Europa League Final.
