Salech's movement for his goal was very good and in his interview he credited Kpakio for the cross.
Salech ran hard for the 6 yard box then dropped back a yard. The defender kept going and left Salech in space. No panic from Kpakio, no speculative ball driven across the 6 yard box, just a cultured pull back. As you rightly say, sublime.
Kpakio is starting to stand out as the pick of the youngsters. When I watched him last year, he seemed to stick to the basics. Didn't get too far forward, always dropping to his defensive position and making short passes to midfielders. This year, the shackles are off. Occasionally gets out of position in defence, but more than makes up for it in attack. Whether that's him feeling a bit more confident because he's had a few games or if it's the coaching and change of game plan. Probably all 3, but I feel it'd the style of play supported by the coaching.
The style still seems to be evolving. Salech's last two have come from overlapping runs. In earlier games the full backs, certainly Bagan, seemed to 'under lap', coming inside the wingers to the corner of the 18 yard box. There seems to be more of the runs on the overlap in the last couple games. It certainly suits Salech more.
I've said it before, it feels like there's more to come from the coaches and the team.
