The France international does not get many starting opportunities in Chelsea as he has only made three substitute appearances in the Premier League so far this season.
Giroud suffered similar fate during the beginning of last season which forced him to mull over a possible departure away from Stamford Bridge, but then reneged on his initial decision to stay.
The 2018 World Cup winner was instrumental as he helped Chelsea secure a top four finish and qualified for the FA Cup final where the West Londoners lost to Arsenal.
Giroud has gone down the perking order following the summer arrival of Timo Werner and he is yet to start for Lampard’s men this season.
Manuello believes Lampard favours Tammy Abraham over Giroud.
He said: “With Olivier Giroud and without the signings, Chelsea were on 18 points from nine matches. These 18 points were gathered when Olivier started seven times. Chelsea scored 18 goals.
“Since the beginning of the season, Chelsea have played eight matches, scored 22 goals and taken 15 points. So if they win their next match, they will equal what Olivier did last year.
“It is not the same to play with (Hakim) Ziyech, Havertz, Werner than playing without them. So we need to look at this relatively. But at the same time you’d be blind not to see that Frank Lampard has decided to put Tammy Abraham ahead of him. It is not frankly fair when you look at what Olivier did at the end of the season. But he has the right, it is his choice.”
“Things have happened in the last five months. We cannot just look at the last two months and be forgetful about the three years that came before it. But we have to be honest and if this continues, we will have to, first and foremost for him, experience other emotions.”
