The goal will give him confidence, sure. All strikers gain confidence from scoring. But celebrate it and now get back into the race again from the beginning and work hard again for the games to come.Pep Clotet.
And whilst the Spanish striker should rightly savour the memory, he must move on quickly.
That's the message from Pep Clotet, who selected Gimenez alongside Lukas Jutkiewicz - who put Blues in command with the first goal.
"Alvaro will remember it, for sure," said Clotet. "English football is very, very special and I am sure he felt it, the emotion.
"When it is at St. Andrew's and when you are a striker, and you score in front of that (Tilton Road) end . . . yes, it's extra special.
"Now it is time to forget it. Dig back, stay grounded, do it again and keep working.
"Alvaro did a good job for the team and he tried to link with with Jukey. It was great to see both the strikers scoring but they have to keep going - this is a tough league and we have a tough game again on Sunday.
"The goal will give him confidence, sure. All strikers gain confidence from scoring. But celebrate it and now get back into the race again from the beginning and work hard again for the games to come."
Gimenez joined Blues from Almeria after the Club met a buy-out clause in the marksman's contract.
It looks to be a shrewd piece of business of the top-scorer in the Spain's second division last season.
However, Gimenez should not be compared to Che Adams, who had a breakout season in the last campaign with 22 goals. That saw him join Southampton in a Club record transfer.
Clotet understands the pressure on his shoulders because of this, and also the departure of Isaac Vassell.
But he says he 'just want him to be Alvaro, not Che'.
“Che had been brilliant for this club. Birmingham has given Che the opportunity to play in the Premier League, he has earned that opportunity.
“I am not looking for Alvaro to be Che, I just want him to be Alvaro. The only thing I want from him is to partner with Jukey and understand how Jukey plays and to use Jukey to establish his own football.
“I am not comparing because at the end of the day they are two different players and the important thing is that Birmingham gives the opportunity to Alvaro to put his footprint in our football.
"This will only happen if he puts himself at the service of the team"
Gimenez's 77th minute goal showed what he is all about. He drifted away from his defender to invite a cracking pass from Steve Seddon and had the calmness to control the ball with his chest before lifting it deftly beyond the advancing goalkeeper.
“The quality of the finish was very good, that ball from Steve [Seddon] was superb," noted Clotet.
“I think he put in a big effort and understood completely what football over here is and he embraced it. He has been one of us from the beginning.
“I am very happy for him and I am very happy for the team because of where we came from.
“Our pre-season has not been the easiest but the team always held together and a lot of the players we managed to bring in came late.
“The fact Alvaro came late and Ivan Sunjic, Fran Villalba and Jefferson Montero - they are just learning how every plays, how the opposition is, what the Championship is about, the aggression and that sacrifice for the team, they are values I feel very happy to have around."
