WATCH: Alexander Lacazette scores on Arsenal debut, Wayne Rooney bags screamer for Everton

New Delhi: Two of the most prominent transfers of the English Premier League 2017-18 season – Alexander Lacazette and Wayne Rooney – got off to flying starts on their debuts for respective clubs to leave fans across the world abuzz on Thursday.

Lacazette, who joined Arsenal for a reported £53 million deal from French side Olympique Lyonnais, came on as a substitute in the 68th minute and opened his goalscoring account for the Gunners by converting a low cross in the box from Alex Iwobi in the 83rd minute against Sydney FC at the ANZ Stadium.

Here's a look at Lacazette's goal:

Rooney, who rejoined boyhood club Everton after failing to confirm a spot in Jose Mourinho's start XI at Manchester United, scored an absolute screamer from way outside the 15-yard box. 

The 31-year-old's 30-yard golazo sent fans and rival clubs a due reminder that his goalscoring days aren't past yet.

Here's a look at Rooney's wonder goal:

Everton, on the other hand, secured a 2-1 win over the Kenyan Premier League club. Kieran Dowell scored the winner for the Toffees with just eight minutes left in play.
