Not for only 4 months.
Say he plays a blinder and then leaves, disrupting the rest of our season?
Utterly pointless for this reason.
Well, not completely pointless in that it perhaps gives us until January to find a striker if none are available now, but you don't buy well in January, so all we're doing is disrupting our side again when leaves.
This is something a Championship side does, not a side of our stature.
