World class attackers make up for a lot of short comings. Look at us with the signing of RVP. So yes, there are other positions that are required, but having a world class attack covers a lot of those mistakes. Also, I don't think the FB issue is as bad as people make out. We just lack attacking output and width. We have Laird who is a genuine world class talent, who won't get a look in because Ole has a hard on for AWB. Williams is a very competent defender and is good at getting forward, but is being forced to play on the left to once again accomodate AWB, which forces him to come in field on his stronger foot. Shaw is our best fullback.
Bailly will end up taking Lindelof's position and is a better defender imo, Tuanzebe if he can stay fit has potential to be our best defender, I still do agree we may need a CB this summer though and a DM, but Matic and Fred rotating, along with our current defensive options isn't as detrimental to us the lack of creativity and output that Sancho would bring.
It's just clear a lot of our 'issues' Ole doesn't see as issues. If he wanted a FB that was going to provide an attacking output, he wouldn't have signed AWB. Everyone and their nan knew what kind of player he was. Especially when we were also linked to Aarons etc. He chose AWB.
