In the current situation, 50 million is a gamble worth taking and 50 million is the new 30 million in today's transfer market. We are never going to blow our entire transfer budget on one player like Sancho, Havertz or even Martinez during this pandemic.
And look at it this way, if Werner really doesn't work out in the No.9 position for us, we can at least still find a place for him out wide as an inside forward etc. We won't have to just toss him aside and given Lampard likes to be flexible with his system/formation, Werner's versatility would be a benefit for us.
