Giroud's switch to Chelsea also gives him the chance to play Champions League football once more, with the Blues facing Barcelona in a daunting last-16 tie that begins this month. The Blues, who won the league last season are now fourth in the league table with 50 points, trailing league leaders Manchester City by 18 points.
Especially if you are a plan b type striker playing for clubs strictly based in London. After 25 games they have won seven, drawn seven and lost 11 times, while they have scored 28 goals and conceded 36 times.
Wenger has attracted flak from a section of the fan base for allowing Giroud to join rivals in Chelsea, but the Frenchman understands why his compatriot wanted to stay in London.
"We know how tight it is and how important wins are".
Giroud made way for 2015 African Player of the Year, Gabon worldwide Pierre-Emerick Aubameyang, who joined the Gunners from Dortmund for a record club fee of 55 million euros.
"We hope they can bring something to the team and help us achieve something this season and in the future".
Chelsea manager Antonio Conte issued a staunch defence of his performance after his side suffered a shock defeat at home to Bournemouth. I think they could do worse than try to sign the Belgian.
It got better for Bournemouth just after the hour mark, as Stanislas punished the Blues with a close range finish, 0-2.
Azpilicueta is possibly the most consistent defender we have and he should start the game at Watford.
'To come away from home and win 3-0 at the champions is a good victory.
And Giroud, who won three FA Cups in almost six years with the Gunners, says Conte's eagerness to bring him across London was a key part of his decision to move.
"We have to understand that, if we want to speak about football and if we think to understand football we know very well this will be very hard for us".
The back three will consist of returning Cesar Azpilicueta, who will be fresh coming into this game.
