Antonio Conte is not happy. Jurgen Klopp and Jose Mourinho are not happy. Arsene Wenger is reasonably happy and so is Mauricio Pochettino.

The happiest of all the Premier League's heavyweight managers is Pep Guardiola. The 2017-18 season starts with differing moods among the men who will contest the title in the world's richest league.

Conte's dark mood surrounds Chelsea's inability/refusal (take your pick) to bring in more players — "the final decision lies with the club," said the Italian leaving no one in any doubt that he is not getting what he wants. Chelsea has not added to the squad, effectively only replacing John Terry, Nemanja Matic and Diego Costa with Antonio Rudiger, Tiemoue Bakayoko and Alvaro Morata and Conte does not believe the squad has the depth to deal with the extra challenge of the Champions League. While Conte did a magnificent job in leading Chelsea to the title using mainly 13 players, he believes the likes of Victor Moses and Marco Alonso may not be able to reach such unlikely heights again and that his side can be as injury-free for a second successive season.
