Striker Lee Erwin said there was no way he could have turned Leeds United down once he learned of the Whites' interest, according to the club's official Twitter feed.
Indeed, the young forward's initial reaction to Leeds' interest will delight all supporters, with the 21-year-old both 'shocked' and 'excited' that a club of the Yorkshire side's stature would want to sign him.
Erwin joins from Motherwell on a three-year deal and feels Elland Road is the best place he can progress.
One of United's biggest weaknesses in the Championship last season was their lack of goals and the hope will be signing Erwin can buck that particular trend.
He told LUTV: "I heard about interest a week before play-offs in mid-May. I was shocked initially.
"I was excited that such a big club were interested. I don't think I could have turned that offer down. This is the best place I could progress."
Clearly, then, Erwin is aware of how big Leeds is in stature, as well as the size of United's support.
He will also, however, be under no illusions as to the pressure and responsibility that will bring.
At 21, Erwin will fit in well with the rest of Leeds' youthful squad, although there is a shortage of quick, young strikers in the senior side. It will be interesting to see who loses out as a result of the Motherwell forward's signing.
