If you look at our goals conceded tally in the past 5 seasons youl find last season was a huge anomoly.
There's no need to panic and fill every hole now. These transitions take time. What if we buy Pepe, he's alright and not world class, we get top 4 and we want Sancho? Ed won't just buy another big signing and put Pepe on the bench. You might as well wait for the big signings when they're available and fill other big holes in the squad in the meantime.
Our right side is a big hole for me, the biggest along with CB in my opinion. Also our biggest problem is scoring goals if you look over same time period.
I'm all for winning games 4-3, 3-2 etc than hoping an average of less that two goals a game scored is enough to win us games. We only won 50% of our league games, that is abysmal to be fair.
I don't believe we are a better team overall than last year after losing Herrera and potentially Lukaku, despite our two new signings. Next season will be a huge struggle. I went against the general consensus on here last summer when I said we would not get top 4, this summer I am even more confident in us failing.
