Fairweather footballers? Not Arsenal, at least not here. Mikel Arteta’s team made light of fierce conditions and desperate opponents to produce possibly their best performance of the season.
Kieran Tierney, Bukayo Saka and Alexandre Lacazette scored beautiful goals and, along with 20-year-old Emile Smith Rowe, delivered outstanding displays, helping to give Arsenal a third consecutive victory and renewed hope of a bright future. For West Brom the forecast is bleak.
