Yep.
Physicality/fitness and prep time is so important. We saw it at Bournemouth at the weekend because they were physically stronger towards the end of the game. Pep even mentioned it in his interviews.
At least before United and Liverpool for the next 2 weekends we are on the right side of it.
We play Tuesday in the Cup and United Wednesday so an extra day there.
Next week we play in a soft-ish home leg on the Wednesday and Liverpool are in Prague on the Thursday. Only Europa Leagiue for them but they still have to put out a team and have the travel as well.
Agree the week after the international break is very tough with Arsenal, Villa and Palace in 6 days. Villa have a day extra before they play us but at least we are at home. Also the Palace game comes directly before the CL QF which could be on the Tuesday, All going to be fun!
