Barely a month has passed since Giorgio Chiellini lifted the European Championship trophy at Wembley, and it would seem logical to expect Serie A to begin amid high fanfare.

This may prove to be the case, as the opening weekend of the season arrives, but a major talent drain from the Italian league since last term cannot be ignored.

Romelu Lukaku, Cristian Romero and Gianluigi Donnarumma have all moved on, swapping Inter, Atalanta and Milan respectively for Chelsea, Tottenham and Paris Saint-Germain.

To put those losses into greater context, of the 2020-21 Serie A end-of-season award winners, that is the MVP, the top defender and the leading goalkeeper all exiting the league.

Sweeping changes on the coaching benches also add to uncertainty as the new campaign begins, with a much-changed Inter hoping to successfully defend their title.

JUVE ON A SCUDETTO MISSION

After the folly of handing dugout rookie Andrea Pirlo the reins before last season, Juventus look to be on firmer ground this time with Massimiliano Allegri back as head coach.

They have brought in Manuel Locatelli from Sassuolo, primed to play a Pirlo-like role on the pitch, and it seems Cristiano Ronaldo will hang around for the final year of his contract.

Rumours continue to encircle the five-time Ballon d'Or winner, but Allegri can likely count on his reliable flow of goals, just as he did for the 2018-19 season – Ronaldo's debut campaign in Turin and the end of the line for Allegri in his first stint as coach.

A six-time Scudetto winner, Allegri will look to get the best out of wingers Dejan Kulusevski and Federico Chiesa as they enter their second seasons with the Bianconeri, while it remains to be seen how Paulo Dybala performs as he enters the final year of his deal.

Plagued by injury last season, Dybala started just 14 Serie A games, but results were often perkier when he played. Of those 14 games, Juventus won 10, drew three and lost one, with a points-per-game average of 2.4 when he played from the off, compared to 1.9 when he was absent or a substitute. The win percentage of 71.4 per cent when Dybala was in the starting XI (compared to 54.2 per cent when he was not) is in the ball park that Allegri will be eyeing.

INZAGHI STEPS INTO CONTE SHOES

Social media tells us Antonio Conte has been thoroughly enjoying his summer, topping up his tan and seemingly showing no regret over his Inter exit, which came in May, just weeks after he guided the Nerazzurri to title glory.

Conte reportedly left amid concern the club planned to raise funds with sales that have duly come to fruition. The loss of striker Lukaku feels like a body blow, given his influence, and persistent rumours suggest Lautaro Martinez could also move on. Achraf Hakimi is another big loss, but, as with Lukaku, a big fee was banked as the right-back proved a one-season wonder in Italy.

In have come coach Simone Inzaghi, who impressed at Lazio, while Edin Dzeko will be a straight swap for Lukaku in the forward line, albeit unlikely to carry quite the same threat. Former PSV star Denzel Dumfries can replace Hakimi in the attacking right full-back role, and Inter will hope his Euro 2020 form transfers to Serie A duty.

It is hard to see Inter repeating last season's success, and the comedown could be painful. They exceeded their expected goals total last season, scoring 84 goals against an xG of 75.3, and Inzaghi will look for more of the same.

They possess plenty of quality still, but they have likely lost Christian Eriksen for the long term too after his cardiac arrest on Denmark duty at Euro 2020. His survival was everything in June, and now his recovery is all-important. The knock-on effect is that Inter have lost a player who became important over the second half of the season.

So much has changed since that title was secured. Landing Hakan Calhanoglu on a free from Milan looks like great business, but consolidation with a top-four finish may be their limit in the new campaign. That, and being sure to secure city bragging rights again.

MOURINHO'S BACK AMID MERRY-GO-ROUND

Never mind Inzaghi and Allegri at Inter and Juve, now is the time to get used to the sound of Maurizio Sarri's Lazio, Vincenzo Italiano's Fiorentina, Luciano Spalletti's Napoli ... and Jose Mourinho's Roma. Milan rather feel like the odd ones out, keeping faith with Stefano Pioli.

A whirlwind of change has swept through Serie A, and it will be worth watching to see quite what impact Mourinho can have on a side who finished 16 points short of the Champions League places last term.

His 'Special One' reputation was enhanced the last time he coached in Italy, guiding Inter to a treble of Serie A, Coppa Italia and Champions League in the 2009-10 campaign.

Spells at Real Madrid, Manchester United, Chelsea and Tottenham have followed, but Mourinho's cachet has diminished over the past decade.

Tammy Abraham has followed him in swapping London for Rome, with the Chelsea striker arriving, along with Eldor Shomurodov from Genoa, to pep up an attack depleted by the loss of Dzeko. Rui Patricio has joined fellow Portuguese Mourinho, and the goalkeeper's arrival from Wolves could prove a fine signing.

Roma won just five Serie A away games last term, and have only had fewer once in a season beginning in the 20th century (4 in 2002-03), while their shot conversion rate of 41.35 per cent can be improved upon, given they topped 50 per cent twice in the 2010s.

Most important for Mourinho, perhaps, will be to build on Roma's poor duel success rate (48.97 per cent) and cutting out the errors leading to goals (10 in 2020-21 in Serie A).

The duel figures are important and were the worst Roma had managed in at least 15 years, while the error count will be simply intolerable to the new boss. Only Bologna committed so many costly errors (also 10). Mourinho has his work cut out.
