April 8 (Reuters) - Arsenal's 1-0 ⁠win over Sporting in the Champions League quarter-final was a ⁠big turnaround for the English club after the back-to-back ‌defeats in the FA Cup and League Cup, attacker Kai Havertz said.

Havertz scored the winning goal against Sporting in the tie after coming on as a substitute ​to give Arsenal an advantage heading into ⁠next week's return leg ⁠in London.
