Having made it to three CL finals and lost twice due to his available alternatives, I'm sure he's grinning while grimacing. For how long was Origi used as a backup CF?
Everything seemed to indicate that the owners wanted to cash in a while back to then end up making this outlay. It's difficult to imagine them not adding more trophies this season if they do obtain Isak as well.
Wirtz is what Havertz was for us a few seasons ago. A potential WC player that would make any team better. If they somehow actually add Isak to the mix, they are addressing their major issues. Also, I don't think enough is being made of their GK signing from last year, Mamardashvili. Having a backup that can actually fill the void when Allison isn't available (becoming more of a regular thing) could help them massively was the worse to happen.
In regard to their key players, if Salah can reach even reach half of his tally from last season (hard to see given the providers they've added, but there's the AFCON) and VVD is solid again, this will be a non-issue.
That's it. This sort of business would have been expected had Salah & VVD left. They immediately replaced TAA, had a goalkeeper lined up from last year, and have improved on areas they've been lacking.
