The Frenchman was in line to leave the club in the summer after appearing to be deemed surplus to requirements at Old Trafford.
Ince believes a welcome return to form over recent weeks should bring an end to those debates, with a man who missed out on World Cup glory in Russian Federation now back in the France squad and offering enough to suggest that he could become the finest deep-lying forward in the Premier League.
However, the France coach warned that a lack of consistency remains a problem for the attacker, who remains immensely talented, and stressed it is up to the player to sustain his performance levels for the rest of the season and take his game to the next level.
United are rumoured to be readying a new £58m five-year contract for the 22-year-old following his inspired turnaround at the club.
The former United midfielder told Paddy Power of a frontman who still has plenty of improvement to come: "No team will want to face Anthony Martial right now".
"I never gave up my feelings that this was the right way for him, even if he had to go through hard moments". It is up to his talent, because he has phenomenal talent.
"It was just a question of him understanding what a top player is because there is a big difference between a top talent and a top player".
"What he does with Manchester United is close to what he is capable of, both in terms of his investment and efficiency".
He's their world class attacking player, the one that can do something special and make things happen when you most need it. He has proved that on the pitch by how important he's been for Manchester United for a few weeks already.
