Chelsea fell to a shock defeat against Arsenal in the Premier League on Wednesday (April 20) evening at Stamford Bridge, and fans directed their anger at a familiar target.The Blues fell twice behind to goals from Eddie Nketiah and Emile Smith-Rowe in a pulsating first half. However, they equalized shortly on both occasions thanks to a deflected Timo Werner effort and a smart Cesar Azpilicueta finish.However, Nketiah's second goal of the game in the second half, plus a late Bukayo Saka penalty, gave Arsenal a vital 4-2 victory. The win stopped their three-game losing streak and moved them level on points with fourth-placed Tottenham.Arsenal@Arsenal WINNING WEDNESDAYS 2-4 (FT)#CHEARS4501612047😍 WINNING WEDNESDAYS🔵 2-4 🔴 (FT)#CHEARS https://t.co/Y1ow0NupkwIt was a lackluster performance from the hosts, who looked to be suffering from an FA Cup semi-final hangover and never really got going in the big London clash.One player who certainly looked hungover was Romelu Lukaku. The 28-year-old returned to Chelsea as the club's record signing last summer, but has been a huge disappointment so far.The forward has only bagged 12 goals in 38 appearances since his £97.5 million move from Inter Milan. However, Thomas Tuchel gave the Belgian a rare opportunity to start against their city rivals.However, Lukaku barely affected the game at all and was hooked off for the team's regular starting striker Kai Havertz just after the hour mark.The Belgian faced huge criticism online from fans after the game, with some offering damning verdicts and embarrassing statistics for the misfiring forward:Squawka@SquawkaAt time of his substitution, Romelu Lukaku had just 22 touches of the ball.Thiago Silva has 20 after 61 minutes...He came on at half-time. 🤯637123At time of his substitution, Romelu Lukaku had just 22 touches of the ball.Thiago Silva has 20 after 61 minutes...He came on at half-time. 🤯 https://t.co/d82KhP0pEGStew ⭐️⭐️@StewartBrown82Romelu Lukaku sweats a hell of a lot for a man that doesn’t fucking move!!!36042Romelu Lukaku sweats a hell of a lot for a man that doesn’t fucking move!!!Alistair Rigby@AliquamScriptoLukaku’s in the top 5 worst PL signings twice.

The Belgian also appeared to criticize Tuchel's tactics and expressed his desire to return to Inter.The former Manchester United and Everton striker has only started 42% of Chelsea's Premier League games this season.Tuchel explained his decision to start the imposing centre-forward before the derby defeat to Arsenal.As per The Mirror, he told Sky Sports:"We want to play with two strikers and Kai is heavily overloaded so was the moment to go with Romelu."Lukaku did score in the reverse fixture on his debut in August. Tuchel added:"If you have a good experience or a good moment against an opponent it can help. It was not the main reason, the main reason was that he deserves to play."Sky Sports Premier League@SkySportsPL🗣️"If you have a good experience against an opponent it can help"🗣️ "He deserves to play!
