Olivier Giroud has revealed the reason he chose to swap Arsenal for Chelsea.

The Frenchman joined the Blues on deadline of the January transfer window in an £18 million move.

Since the switch, Giroud has bagged three goals, two of which came today as Antonio Conte’s side pulled off a remarkable turnaround from 2-0 against Southampton to win 3-2.

The France international’s sale was questioned by many Arsenal fans, with the striker a fan favourite at the Emirates.

However Giroud says the decision to move to Stamford Bridge was simple.

“Chelsea are a massive club and we want to challenge for the title every single year,” he said.

“Obviously the competition has been the toughest this year — with Man City, Liverpool doing well, Man United, even Arsenal.

“That’s why I love the Premier League, it’s the best championship, it is very hard.

“I am a competitor so hopefully next year we will compete for it.”
