Neymar, Icardi, Messi, Sarri - this week's big talking points in European football

[#DEXTER]

 

After the international break, domestic top-flight football returns to Europe's top leagues this weekend.

Will Neymar make his first appearance of the season for Paris St-Germain? Is Mauro Icardi already unhappy at PSG just days after completing a loan move from Inter Milan?

And could Lionel Messi really be nearing the end at Barcelona?What kind of reception will Neymar receive?

Having turned out for Brazil during the international break, Neymar could make his first appearance of the season for Paris St-Germain on Saturday.

The question is: having pushed for a move away, what sort of reception will the forward receive?

Neymar, 27, suffered an injury to his ankle on international duty in the summer and has yet to play for PSG this season.
