Graham Potter insists that he's not experimenting at Chelsea, but maybe he still is. He has the plan and the ideas, he knows how he wants his team to play, but the former Brighton manager is working out the best way to go about it at Stamford Bridge.
His inverted wingers at wingback with a natural No.10 operating more as a deep-lying playmaker with a competent short-passer in goal and unorthodox and dynamic centrebacks don't just reappear at SW6. He can bring the tools, the staff, the knowhow and the blueprint, but he can't bring the finished product.
To this extent, trying players in different positions to see how they gel is an experiment, it's a test of the circumstances, it's an examination of his squad in new a situation, it's an inspection of quality and fit.
