"Purple patch lasted less than a month" "Bottled 3 big chances" - Chelsea fans bemoan 22-year-old's forgettable display against Manchester United  

Chelsea put on a dominant first-half display against Manchester United in Thursday's Premier League clash at Old Trafford. Despite all their pressure, however, the game remained goalless at half-time.

The Blues took 11 shots, five of which were on target. Thomas Tuchel will be furious that his side failed to capatilze against a dismal Red Devils, who looked bereft of any confidence.

Several David de Gea saves have kept Ralf Ragnick's team in the contest.

Tuchel's men have torn the hosts to shreads on the right flank, with Reece James having a joyous 45 minutes against a helpless Alex Telles.

Many inside the stadium will be wondering how Chelsea didn't score, with Kai Havertz in particular missing some gilt-edged chances.

The German wasted an opportunity when passing looked like a better opportunity and headed poorly at the keeper from eight yards out, wasting a pinpoint James cross.

The former Leverkusen forward had his best opportunity just before the break when he found himself one-on-one with De Gea, but fired his effort tamely at the Spanish shot-stopper.

Blues fans have taken to social media to criticize the 22-year-old's performance:

Havertz continues difficult Chelsea run with poor first-half against Manchester United

The Germany international has become Tuchel's first-choice centre-forward this season following poor form of record signing Romelu Lukaku.

Havertz, who scored Chelsea's winner in last season's Champions League final victory against Manchester City, has netted 13 times in 42 appearances this term.

He developed a reputation as a big-game player following his Champions League winning goal. He also scored the decisive penalty in the West London side's Club World Cup final triumph against Palmeiras in February.

He recently went on a run of five goals in five games across March and early-April. However, he has since netted just once in his previous five Blues appearances, while missing a host of chances in the process.
