Mkhitaryan had struggled to adapt to life in England following his big-money summer move to Manchester United from Borussia Dortmund.
But he silenced his critics by netting in three consecutive games last month including a goal-of-the-season contender against Sunderland.
Liverpool legend Carragher believes that sublime strike could set Mkhitaryan on the path to achieving great things with United.
He said on Sky Sports: “It was unbelievable skill.
“The brilliant thing about that goal was that Mkhitaryan was starting to show signs that he was ready to show everyone in the Premier League what he’s all about.
“That goal was showing he’s here and he’s arrived.
“That goal, in the next few years, we could be saying that was the real starting point for him going on to be one of the top players in the Premier League.”
