Arsenal are moving to secure the long-term future of their lethal strike force Alexandre Lacazette and Pierre-Emerick Aubameyang.

The duo were the goalscoring heroes against Valencia in the Europa League semi-final. Arsenal scored seven goals over the two legs — Lacazette with two and Aubameyang once in the 3-1 win at the Emirates, before Aubameyang scored a hat-trick and Lacazette the other in a 4-2 victory in Spain.

Talks are planned this summer to extend the contracts of the pair as Arsenal look to avoid further loss of key players.

FINAL-DAY HAT-TRICKS There have been 13 hat-tricks on the last day of the season since the Premier League started — four by Arsenal players. Advertisement

The trend started back in 2012 when Robin van Persie was had one year left on his deal and Arsenal decided to cash in by selling him to Manchester United for £22.5million rather than lose him on a free transfer the following summer.

The club were faced with a replica scenario with Alex Oxlade-Chamberlain two years ago.

He also had 12 months left and with no new contract agreed, Arsenal sold him to Liverpool for £35m.

Aaron Ramsey will leave on a free transfer to Juventus because he is a free agent.

The fans are furious and Arsenal will now act to prevent similar situations arising with Aubameyang and Lacazette.

Gabon international Aubameyang remains in contention for the Premier League Golden Boot with his 20 goals going into Sunday’s final match at Burnley.

He is two behind Mo Salah of Liverpool and on the same total as another Anfield striker, Sadio Mane, and Manchester City’s Sergio Aguero.

He has proved to be a major asset since his £56m move from Borussia Dortmund in January last year. The 29-year-old has two years left on his £190,000 a week contract. Arsenal want to extend it by two years and that would put 29-year-old Aubameyang in the £250,000 a week bracket.

A similar wage would be offered to France international Lacazette. The 27-year-old has scored seven goals fewer than his strike partner but he has proved an ideal complement. His deal expires in 2022.
