The Manchester United striker got on the score-sheet at Wembley as he helped Gareth Southgate’s men to claim three points and secure their spot at Euro 2020.
Rashford and most of his Manchester United team-mates have struggled to find consistent form for most of the current campaign and the Red Devils are down in seventh place in the Premier League table.
However, Rashford impressed alongside his England team-mates on Thursday night and he has now scored six goals in his last seven appearances for club and country.
And former Manchester United captain Keane feels that Rashford has rediscovered his confidence in recent weeks.
Speaking to ITV Sport on Thursday night, Keane said: “He looks like he has got his confidence back, I think in the last month or so.
“And what players have to remember, when we’ve been criticising them before, there’s a compliment in there because we believe he’s a really good player.
“His confidence is up and running again and he looks back to his best.”
Rashford has scored nine goals in all competitions for Manchester United so far this season.
The young striker will be hoping to feature for the Red Devils when they return to Premier League action after the international break with a trip to Sheffield United next Sunday.
The Red Devils have so far only managed to win four of their opening 12 Premier League games under Ole Gunnar Solskjaer.
