If I were someone looking at this and making a decision on behalf of NTFC about Chankas credentials for leading our line and us towards promotion, I'd discounting any footage with trees in the background.
Although a few of them were Cardiff's training pitch so probably a better surface than most L2 grounds. I take your 'trees in background' and raise you 'goals on wheels'.
Looks handy though. A lot of the goals (only watched a couple of mins I'll be honest) showed good movement and getting on the end of good balls. Something I dont think will apply to his time with us.
Good Luck and make us all forget the name of the bloke from Spurs.
