It doesn't if you spend it idiotically like we did with Walsh in charge.
Frankfurt got Haller, Jovic, Rebic and Kostic for just over 20 mil altogether, Dortmund just got Brandt, Hazard and Schulz in for about 70 mil, Watford got Richarlison, Doucoure, Deulofeu in for about 30 mil.
I agree, I think Lookman has bags of talent, I've watched Vlasic regularly this season and been impressed, I think Onyekuru would be a weapon for us just through his sheer pace and I'd love to see them all in the first team but I doubt that will happen. I think we risk stunting their development if they spend a season here just being wasted as bit-part players and their values would diminish.
