The Leeds United youngster is now back at Elland Road following a brief loan spell.
The former Motherwell striker spent 28 days on loan at the League One side, making three appearances in the process, and while he failed to score he is expected to have a very bright future at Elland Road.
With Evans’ preference to play two up front, there could yet be chances for Erwin to impress this season either from the bench or if Mirco Antenucci or Chris Wood are unavailable as the campaign wears on.
Prior to his move to Leeds, the 21-year-old showed his eye for goal with a fine end to the Scottish Championship season, scoring six goals and providing six assists in his last 11 matches.
Yet to make his first-team debut for Leeds, things could soon change following his return to the club, and Evans has explained what he will be saying to Erwin in a bid to get him ready for the senior side.
“I rang him as soon as I took over to remind him that I’m a manager who was keen to try to secure his services (while at Rotherham),” Evans told leedsunited.com.
“I’ll also be having a chat with him this morning about my opinion on where he’s been to how he’s going to have to play. It really is a big step up in terms of the quality of opposition.”
In time Erwin has all the attributes to succeed at Leeds and, while he is only likely to be used sparingly in the short term, fans of the club could soon see why Evans was so desperate to sign him in his former role.
