Until then, he was having a tough night, struggling to impose himself in the game and looking isolated upfront.But the goal will do a world of good to the beleaguered striker's confidence as his Stamford Bridge return has been marred by injuries.Lukaku rejoined the Blues last summer in a sensational move from Inter Milan for a staggering £97.5 million. However, his second stint with the club hasn't gone according to plan.He's missed nine games through a hamstring problem and COVID-19 infection, while an outrageous interview in January drew plenty of criticism too.Last night, the 28-year-old bagged only his 10th goal of the season from 29 games in all competitions, but it could prove to be one of the most important ones.Despite a poor game, the Chelsea striker came up clutch when a glorious opportunity presented itself, something that will boost his confidence going forward.On that note, here are some of the best reactions to Lukaku's performance from the fans:Austin3x@tenixe3@brfootball Found his level against Luton3:06 AM · Mar 3, 2022@brfootball Found his level against Lutonthe twenty-second pilot 🙋@CaptainNuel_@brfootball Maguire vs San Marino vibes...2:37 AM · Mar 3, 202213@brfootball Maguire vs San Marino vibes...MENE MENE@_Bongani__Lukaku must play more of these cup ties10:07 AM · Mar 3, 2022Lukaku must play more of these cup tiespoco mongs@ChristophLavens@ChelseaFC @VermeylenS What a player.
