If you think we only have 13 good players then you are pretty clueless IMO. How have we won what we have and got to a C/L final with only 13 good players, thats a ridiculous suggestion, especially when we rotate so much.Ironically with hindsight you are now saying it was the right decision. Either way De bruyne not playing wasn't the problem. Tactics and slow build up with no end product was.
Now either we have a good squad or we don't, personally I think after the first 13 or so we don't.
