The Frenchman enjoyed a sensational debut campaign Old Trafford, netting 17 goals, but has struggled to impose himself under Mourinho this season.
That said, his performance against West Ham – characterised by a series of powerful bursts forward and two well taken goals – on Wednesday night evoked memories of last season.
Redknapp, speaking after Man United’s 4-1 win over Slaven Bilic’s men, claimed that Mourinho would be foolish to let the 20-year-old leave Old Trafford any time soon.
“Granted, he hasn’t had a good season – he has been struggling for a while now. But he’s the sort of player that if you let go, he could end up being another Kevin De Bruyne or Juan Mata.
“He is a top talent. He just needs an opportunity.”
The Martial of this season has been a notably reserved figure. That insatiable desire to burst past defenders at will has nowhere been essentially non-existent, and in its place came a cautious approach that placed emphasis on simply not losing the ball. Whether such a change of tack can be attributed to a change of style under Mourinho, or simply because of a post-Euro 2016 hangover, is hard to say.
Either way, what United fans witnessed on Wednesday was hugely encouraging. The youngster was fearless, decimating Pedro Obiang on the left hand side on several occasions with his sheer bloodlust on the ball.
There was a moment last night where Martial tore forward, at a speed hardly seen this season, towards the box from the left hand side, with Obiang the only thing between him and the goal, and everybody knew – and by everybody I mean Old Trafford, the watching world, his teammates and Obiang himself – that Martial couldn’t be stopped. He was ultimately fouled because, let’s be honest, that’s the only way to stop the Frenchman when he hits such a ferocious speed.
United fans will be hopeful to see more of the same from the Frenchman in the coming months.
