Massimiliano Allegri’s Juventus, which is chasing an eighth consecutive Italian league title, has now won its opening five league games for the third time in five seasons. Ronaldo was the hero, days after being sent off on his Champions League debut for the Turin club, breaking the deadlock from close range in the 81st minute to take his Serie A tally to three goals in five games. 

The well-drilled host, which has picked up just one point this season and is still waiting to score its first goal, provided a surprisingly stern test for the champion but its challenge ended in stoppage time when Federico Bernardeschi finished off a counter attack to put the result beyond doubt. “We expected it to be like this,” said Allegri. “Frosinone had conceded five to Sampdoria and we played down to 10 men for 70 minutes against Valencia (in the Champions League) on Wednesday.” 

Juventus leads the Serie A standings with a maximum 15 points from its opening five games. Bologna went into the game without a win or a goal to its name this season but strikes from Federico Mattiello and Federico Santander gave Pippo Inzaghi’s side its first home win against the capital club since 2004 and left Roma in 14th place with five points.

Paris St Germain stretched its perfect Ligue 1 start to six wins after coming from behind to beat Rennes 3-1 away in a rip-roaring clash.

PSG’s victory kept it top of the French league on a maximum 18 points, five clear of second-placed Lille, after Angel Di Maria and Thomas Meunier cancelled out an early Adrian Rabiot own goal which fired the adventurous home side ahead. Second-half substitute Eric Choupo-Moting added the third goal in the closing stages for the visitor.
