BIRMINGHAM, England (Reuters) -Chelsea responded to a troubling week with a superb 3-1 win at Aston Villa to reach the fifth round of the FA Cup and put a smile back on the face of Mauricio Pochettino on Wednesday.
Successive heavy losses in the Premier League had left manager Pochettino under intense scrutiny ahead of the fourth-round replay, but first-half goals by Conor Gallagher and Nicolas Jackson put Chelsea in control before Enzo Fernandez delivered a sublime free kick after halftime.
