LuaLua was injured towards the end of last season
DR Congo's Lomana LuaLua insists he will "let the football do the talking" after finding reports concerning his private life overshadow his recent performances.
The Portsmouth striker was arrested but released without charge two weeks ago following a domestic incident.
But the 25-year-old believes there are critics with an agenda looking to drag him down.
He said: "It's been a difficult time but sometimes it is better to let the football do the talking.
"The rest of it is all nonsense. It's just rubbish. I'm just happy to be back playing again. I'm getting my fitness back and focusing on getting sharper.
"I'll focus on that because that is what matters. All the other stuff is just talk. Well, let them talk."
LuaLua was struck down by malaria while on international duty in September last year, and in January lost his baby son, named Jesus, to pneumonia.
His season ended in April when he damaged an ankle after scoring his fourth goal in four games while performing a trademark "somersault" celebration against Arsenal.
And he was unable to regain his first-team starting place until earlier this month in a disappointing display against Tottenham, even though he almost grabbed a last-gasp equaliser.
He said: "It seems like the devil is always trying to get God's child. People can keep trying to bring me down but they will never catch me."
