Bukayo Saka celebrated signing a new long-term contract by helping Arsenal deliver a blow to Wolverhampton Wanderers’ hopes of Champions League football next season.

The 18-year-old, who delighted manager Mike Arteta by pledging his future to the club, demonstrated why he is so highly regarded by scoring his first Premier League goal – a sweet, left-foot volley just before the interval.

And the Gunners made it four successive victories when Alexandre Lacazette capped a fine team display by turning on fellow substitute Joe Willock’s pass and firing emphatically past Wolves keeper Rui Patricio with five minutes left.
