Arsenal were knocked out of the Champions League by Monaco in March but won all four for their Premier League matches against Everton, QPR, West Ham and Newcastle.
Giroud bounced back from being substituted just an hour into Arsenal’s Champions League first-leg defeat against
Monaco by scoring six goals in all competitions, averaging a goal every 78 minutes from 17 shots.
Wenger told Sky Sports News HQ: “You just focus on the next game and it reminds you that you have done well in the last month, but you focus on the next one.
“Winning is a mixture of quality and disappointment because we have gone out of the Champions league and that was a disappointment, but overall we are on a strong run in the Premier League and the FA Cup so it is mixed.”
Giroud, who has prevented Tottenham striker Harry Kane from becoming the first player to win the prize three months in a row, says winning the award shows his strength of character.
He said: “I am in good form and it’s nice to win this trophy and it will be nice in my living room.
“After the Champions League I was really pleased to score and bounce back and come back stronger.
“I don’t like when I miss a game and I want to show my strength and character. I needed to score straight away after the (Monaco) game to keep confidence and to help the team to reach our target in the Premier League.”
Wenger added: “Giroud is the symbol because in the first game against Monaco he got a lot of criticism and he responded to that with very strong performances – that shows quality and mental strength.”
