Allan laughs when it is suggested his son might favour wearing an Everton shirt over a Cristiano Ronaldo one if the Toffees win the FA Cup.
But he is serious when he says his boy is one of his main motivators.
Allan, 30, recently allowed his son nine-year-old Miguel – who has alopecia – to shave his head in solidarity with his boy.
“We do everything for our children, we do everything possible to make sure they’re happy and they are safe,” said the Brazilian, who Everton signed from Napoli last summer.
“He loves football, he’s always watching football, he is always in an Everton shirt and shirts of the other team I played for.
“He’s my greatest motivator, him together with my daughter at home.
“You always have that family strength.
“When you go on the pitch, they give you strength, they motivate you and drive you and you want to play to always make them happy.”
The skin-headed Allan only made him even more fearsome looking on the pitch.
“My face doesn’t really help but it is not a problem as I am married and have three kids and my wife finds me attractive whichever way I present it [hair],” he joked.
But as a hard-tackling midfielder, the father-of-three admits it is still a battle to be his children’s favourite player.
“They are big fans of Cristiano Ronaldo so he has always had a Ronaldo shirt, however he is not allowed to have a Ronaldo Juventus shirt because they are massive rivals of Napoli, so there are a lot of Real Madrid No 7 shirts at home.
“That is normal. The kids always dream about scoring goals and idolise the goalscorers, my son is no exception.”
Allan has recently returned from a hamstring injury which kept him out for almost three months after a positive start to life at Goodison Park.
But he is back now to help the Toffees push for a top four finish in the Premier League and a bid for silverware in the FA Cup.
They face Pep Guardiola’s all-conquering Manchester City side this evening in the quarter-finals, though.
After their recent defeat by City in the league, Everton boss Carlo Ancelotti admitted it was “almost impossible” for the Toffees to compete with the soon-to-be champions.
“We know about the quality of Manchester City and they are having a very good season but Professor Carlo has prepared us really well,” said Allan.
If the Brazilian helps end Everton’s 26-year wait for a trophy then there might be more than just his son wearing his No 6 on their back as he will go down in the club’s history.
“We know this competition is a priority for the team, it is important and we are only a few games away from lifting a trophy so it is an opportunity,” he added.
