After the international break, domestic top-flight football returns to Europe’s top leagues this weekend.
“What’s been really interesting so far, even though Sarri has not been in the dugout, is that he has picked more or less the same team as the former boss Massimiliano Allegri did,” said Horncastle.

In a scene straight out of DIY SOS, Napoli have posted a video on Twitter showing their unfinished dressing rooms with scaffolding still in place, pots of paint on the floor, sinks missing and electrical sockets unfinished.
Napoli boss Carlo Ancelotti said he is “shocked” by the state of the dressing rooms following renovation work at Stadio San Paolo.
The Serie A side played their first two games of the season away from home but host Sampdoria on Saturday before holders Liverpool visit in the Champions League on Tuesday.
“It’s a disgrace that a club as big as Napoli, in the Champions League, have what is essentially a stadium that is unfit for purpose,” added Horncastle.
“This is a common problem in Italy.
“Most of the stadiums are run by the council and I think with Ancelotti going public on the club’s website with this is very much the club taking a stand against the mayor of the city.”
