Myself and Malcolm share the same birthday, although I’m a tad older

Looks to have talent and potential from the clips available of him.
He looks to be another left footed right sided attacker who favours cutting in from the flank.
That makes 3 who perform in a similar fashion if you include Olise and Rak Saki.
I don't envisage he will challenge Olise for the position in the near term but he could hold back the development of Rak Saki.
I suppose it must be likely that one of them will be loaned out next season to gain experience.

I don't think it's comical at all. Not all transfer decisions (by players) are purely financial. Most want to feel wanted and there are plenty of examples of players choosing clubs because they had a better experience with that club during the recruitment process. If the club is prepared to drive to your house to get the deal done, vs another who sends a text message, it can clearly make a big difference.

Ye I'd certainly agree... after reading the article it was more just the comical vision I had in my head of Dougie stalking the lad and wee Malcolm probably barely understanding a word Dougie is saying

I notice that while he has represented England U16, he has also played for the Netherlands at U15 level.

One possible word of caution is that Arsenal supposedly let him go as a youth player due to concerns over his work ethic. Sometimes that is the kick up the proverbial a player needs, but we shall see. Unlike Olise and Eze, I doubt he's been brought in as someone who will immediately challenge for a starting sport, but you never know. An exciting addition nonetheless.
