If anything, it's baffling that there's so much negativity about this from some people.
He's relatively young and hasn't played that much first team football before (so probably still has quite a lot of room for development).
He's on relatively low wages, and has sell-on value even if he doesn't progress that much more.
He's shown that he can improve, and clearly suits Ten Hag's system.
He's versatile and can play LB relatively well as well (or has people forgotten how he filled in at LB after Malacia's nightmare?)
And with FFP, even with new owners, there's a real limit as to how much we can spend this summer.
Really, I'm not sure if I can see a real downside to this deal. At worst, he could be sold on in winter or next summer without a huge loss. What's people's problem with this deal? Even during SAF's years, we've had average squad players who's stayed because they can be relied upon to put in a shift when need be (O'Shae, Brown, etc....). With the overhaul that's needed in this squad, an average RB who can still improve is hardly someone we should throw away this summer. (People clearly plays too much FM and believe that we can replace half of the first team squad and half the substitutes in one summer....., I recommend people to actually learn a bit about modern football first....)
