Mate, they're completely different. No idea how many times you've seen Skipp play but he's completely different to Winks in every way besides the fact he's white and came through the youth.
Not persuading myself nothing. I've seen both play numerous times in youth football for us and 50+ first team games between them and not a single time within that time have I ever thought they were similar in a single way.
Not really sure how the comparison is ludicrous. One aims to keep possession and control a game whilst the other aims to break up play and is more defence minded.
Only ever seen Skipp since he's broken into the first team. I'd never play him and Winks together. Both ball winners/recyclers playing in front of the defence. Both there to break up play and act as an outlet when a teammate is looking for a pass. Similar build/height/weight. Both inexperienced. Skipp maybe has more potential.
In my view they are very similar (like the other pairs I've quoted that can't be chosen together - unless in an emergency).
I've given my views as to how I think they're similar. Rather then how many times you've seen them, tell me how you think they're not.
We'll see if the manager agrees or not.
