Edinson Cavani replaced Martial as Ole Gunnar Solskjaer’s first-choice up front last season with Ronaldo’s sensational return to Old Trafford forcing him further down the pecking order.
Competition on the left where the Frenchman has regularly played over the years is also intense following Jadon Sancho’s arrival from Borussia Dortmund.
And Berbatov believes Martial could be one of the first to leave if he is not given enough game time this season.
‘This is my only regret of this [Ronaldo] situation, maybe Anthony is a bit left out and maybe he is going to be the casualty of all this,’ Berbatov told the Manchester Evening News.
‘But we don’t know yet. We can speculate as long as we can but maybe he will surprise everybody with even harder performances on the pitch.
‘Because Ronaldo is in the team automatically, everybody else – especially the young players – will want to raise their game and bar, performing on the training pitch and in the games.
‘In the case of Anthony, if he doesn’t get playing time as much as he wants then I will see him leave the club at some point, to be honest.’
The Bulgarian believes his former Monaco teammate can still fight for his future, however, by showing Ole Gunnar Solskjaer he is desperate to regain his place in the side.
‘My advice is maybe to be a bit more open, a bit nastier, but not nasty like hitting people around like a defender, but more, ‘I want to be first-choice. I want to prove how good I am.’ A bit more of that nastiness to show the manager that ‘I am here, I want to stay and fight for my place’.
‘If that doesn’t happen, the quality in him is there to go to another place and look for his luck there.
‘I have my soft spot for Anthony because I played with him, he has great qualities. But if it doesn’t work and he’s not playing, he should go somewhere else.’
