The Leeds United youngster will surely play a role in the months ahead.
After three appearances and no goals, Erwin returns from his 28-day emergency loan no doubt hoping he will get chances under his new manager, having yet to make his Leeds debut despite signing from Motherwell in the summer.
Prior to his loan switch Erwin had to make do with under-21 football and in the short term, while Evans assesses his ability, that may be the best he can hope for; but once he is up to speed there is every chance the 21-year-old could prove to be Leeds’ secret weapon in the months ahead.
With Evans’ preference to play two out-and-out strikers, the need for Erwin as the campaign draws on could well mean the young Scot is destined to play a fairly significant role in the second half of the season.
After all, Chris Wood and Mirco Antenucci cannot be expected to play week in, week out, and for now Leeds’ only other striking option is Souleymane Doukara.
Evans recently admitted to the club’s official website that he tried to sign Erwin when he was the manager of Rotherham United, so he clearly rates the player.
Then there is the fact that Erwin ended his final season at Motherwell with six goals and six assists in his last 11 matches; the kind of form that suggests he could be exactly what Leeds need when games are as close as they have been practically all season.
To have that option from the bench is something Evans will not turn his back on, and while January could see more new strikers arrive, expect Erwin to make his mark before May.
