=== Februari ===
Pada 5 Februari, Chelsea dikalahkan oleh Watford 4-1 di Vicarage Road. [[Troy Deeney]] membuka skor dengan gol dari titik penalti setelah dihalang oleh Bakayoko, kemudian, Bakayoko harus menerima kartu kuning kedua dan dikeluarkan setelah bermain hanya selama 30 menit saja. The Blues bermain satu jam dengan 10 pemain setelah kartu merah [[Tiemoue Bakayoko]] untuk menutup penampilan individu yang mengerikan selama 30 menit - di mana ia memberi Watford empat peluang. The Hornets - yang hanya menang satu dari 12 pertandingan Liga Premier sebelumnya memimpin secara kontroversial ketika [[Gerard Deulofeu]] turun dengan mudah di bawah kiper [[Thibaut Courtois]], [[Troy Deeney]] kemudian membuka skor melalui penalti. Chelsea, yang membawa [[Olivier Giroud]] untuk debut di babak kedua, mencetak gol penyeimbang ketika [[Eden Hazard]] meringkuk dengan gemilang dari jarak 25 yard. Namun, dua menit berselang, [[Daryl Janmaat]] mencetak gol fantastisnya sendiri ketika ia memotong dari sayap kanan, bermain satu-dua dengan [[Roberto Pereyra]] dan mengalahkan pasangan bek lainnya sebelum mencetak gol-golnya menggunakan kaki kiri. Deulofeu menambahkan gol yang lain ketika ia berlari dari setengah sebelum tendangannya mengarah ke kandang oleh [[Gary Cahill]] dan Pereyra mencetak gol keempat dari bola yang diterima [[Abdoulaye Doucoure]]. Deulofeu mendapat Man of The Match dalam kampanye ini.<ref>{{Cite news|url=https://www.bbc.com/sport/football/42855189|title=Watford 4–1 Chelsea|publisher=BBC Sport|date=5 February 2018}}</ref>
