I can see where you are coming from! There is some truth to it!They are both the same height (1.7m) and build....but it's the manner in which Lucas puts himself about that puts me in mind of Defoe. Very similar style in my view.
But I would not be quite as harsh. Because let's face it - we liked Defoe, quite a good servant to the team. But at the same time when we look at where we have come to... he wouldn't really cut it in current Spurs team. Well, mainly ofc because of Kane. He could be like Llorenteesque player from the bench if other options are used, but not much more.
I think Moura has pace on his side, he works quite hard on the field (tracking back) and i HOPE that his decision making / reaction speed could be coached bit better . I mean the tecnique and abiltiy should be there - he is Brazilian still
