Alphonse Areola - Made a couple of good saves in the first-half but could not stop Joseph Paintsil's shot. A virtual bystander in the second period, nothing he could do about the late own goal. 6
Vladimir Coufal - Continued his recovery from fitness with valuable minutes, work hard and was one of the least bad players in the first half, not that that is saying a lot. key to the equaliser with a fine run and pass to Benrahma. 7
Craig Dawson - Huge threat at set-pieces and was trying to rally the troops throughout a poor first half. 6
Issa Diop - Poor start to the match from Diop, could have done better on Paintsil's goal and too often gifted the ball to Genk when under little pressure. 5
Aaron Cresswell - Was unable to get forward as often as when playing behind Benrahma with Masuaku occupying his space. 6
Mark Noble off 58- Caught in possession on occasion and off the pace at times. Too easily bypassed in midfield. 4
Declan Rice - Rightly booked for a poor tackle in the first-half, started uncharacteristically slowly but grew into the game. 6
Arthur Masuaku off 58 - His tendency to run on the outside of the right-back hampered Cresswell's efforts on the overlap. Looked like a lack of understanding between the two. Poor performance from the wide man. 4
Said Benrahma - Showed flashes of skill but too often made the wrong decision with the final ball in the first-half. Fine finish for the equaliser which seemed to boost his confidence as he improved towards the latter part of the match and capped it off with a simply superb second goal. 7
Manuel Lanzini off 85- Wasted possession and was on the periphery of the game for much of his time on the pitch until playing in Coufal with a lovely pass to set-up Benrahma. 6
Michail Antonio off 58 - Poor night for the strikers return to European action and rightly substituted before the hour mark. 5
Substitutes -
Tomas Soucek on 58 - More dynamic than Noble and gave Rice the support the captain had failed to do. Unfortunate to concede a late own goal when stretching for the ball. 6
Pablo Fornals on 58 - Looked dangerous on the counter-attack and tracked back well to help out Cresswell. 6
Jarrod Bowen on 58 - Very lively after his introduction providing pace to the West Ham attack. 6
Alex Kral on 85 - n/a
