Liverpool officially announced Iraola as the new manager, and all of the Premier League's Big Six clubs now have young head coaches.

Following Liverpool’s announcement of Iraola as the new manager, the head coaches of the Premier League’s elite clubs have largely all entered a young-coach era. The primary reason Liverpool opted for Iraola is his exceptional tactical acumen. His notable accomplishments include taking Rayo Vallecano up to La Liga and leading Bournemouth to set new club Premier League points records in three straight seasons, as well as earning the club its first ever European spot (Europa League).

The Premier League's Big Six have all entered the young-coach era:

• Liverpool: Iraola, 43, newly appointed and officially announced.
• Chelsea: Alonso, 44, newly appointed and officially announced.
• Manchester United: Carrick, 44, made permanent and officially announced.
• Arsenal: Arteta, 44, won the Premier League title last season for the first time in 22 years, and finished as runners-up in the Champions League.
• Tottenham: De Zerbi, 46, took over at the end of last season and successfully kept the team in the top flight.
• Manchester City: Maresca, 46, confirmed by Romano, but due to compensation issues with Chelsea, the announcement has not been made yet; however, it is certain that he will replace Guardiola.

Look at the coaches of England’s top teams, then look at those of Italy’s top clubs (the same few Italian journeymen rotating in and out). A good coach can accelerate a team’s development, making the Premier League full of passion and excitement. In contrast, the Serie A has become slower and slower, lulling fans to sleep. The gap between the Premier League and Serie A may very well start with the coaches.
