In the shootouts, though, he found no luck.Diogo Dalot - 6.5/10He wasn't really called into action either, but at least dispatched his penalty in the shootout.Raphael Varane - 6.5/10The Frenchman had an easy game but still needs time to return to his best following a lengthy injury lay-off. He was taken off before stoppage-time.Harry Maguire - 5/10The Manchester United skipper was in no man's land for much of the game and came a cropper during the equalizer too. He did salvage some pride with a successful penalty in the decider.Luke Shaw - 7/10Shaw sprinted forward with a lot of energy, purpose and vision. He completed five key passes and won eight ground duels.Paul Pogba - 7/10The Frenchman played his first match since November and performed well, winning a penalty early on and making one crucial ball recovery which also led to their first goal.Scott McTominay - 6.5/10McTominay worked hard in midfield to keep everything ticking for Manchester United. He won nine ground and aerial duels each, made four interceptions and three tackles.Marcus Rashford - 6/10He saw a goal disallowed for offside but got into some good positions which needed Middlesbrough's attention. Too bad he wasn't on the pitch to take a penalty owing to his withdrawal in the 82nd minute.Bruno Fernandes - 5.5/10Fernandes assisted Sancho's goal with an excellent pass but saw an effort of his own come off the post. He visibly waned after the break but had enough in the tank to score in the shootout.Jadon Sancho - 7/10The England international was vibrant in the first half. He chipped in against the bar early on and then put Manchester United in front with a well-taken finish but faded in the second stanza.UTD@utdzonevidJadon Sancho’s goal against Middlesbrough 2:00 AM · Feb 5, 20222818303Jadon Sancho’s goal against Middlesbrough 🔥 https://t.co/3CKdtSFn5FCristiano Ronaldo - 5/10The Portuguese talisman missed a penalty and wasted a few more good chances on a torrid evening, but saved face by converting from 12 yards in the shootout.𝐀𝐅𝐂 𝐀𝐉𝐀𝐗 💎@TheEuropeanLad📸 - Ronaldo MISSES the penalty!1:52 AM · Feb 5, 20226383309📸 - Ronaldo MISSES the penalty! https://t.co/lvia4uuIXqSubstitutesFred - 6/10He scored in the shootout, besides which there was nothing much to see.Anthony Elanga - 6/10The youngster looked to get involved right after coming on and looked dangerous aerially.
