To be fair Trenchin are/were a partner club with Ajax much like Ajax Cape Town.
The idea was to play the same way as Ajax and for them to recruit the prospect from Eastern Europe or oversea's who couldnt either go straight to Ajax or needed to be developed and play in the same system.
So technically the bloke is probably ok, is 21, can develop and could be a low risk high reward signing, not seen any of trenchin obviously.
