Andrea Pirlo is not overly concerned by Juventus' poor run of form, although he knows his team must return to winning ways when they face Crotone on Monday.

Juve have not won in three matches in all competitions, following up a 0-0 Coppa Italia draw with Inter – which nevertheless secured their place in the final – with defeats to Napoli in Serie A and Porto in the Champions League.

Their performance against Porto was particularly lacklustre, but Pirlo believes the fixture congestion since the turn of the year is a major factor.

The Bianconeri played nine times in January and have been in action on a further five occasions in February, with two games every week in 2021 until now.

"I speak with the president after every game. We spoke after the game at Porto and he didn't intervene this week," Pirlo told a news conference on Sunday.

"We knew we had played a bad game, there was no reason for him to reproach the team. I raised my voice during half-time in Porto, I didn't like how we played and I didn't like the reaction.

"We switched off at the beginning of the second half and we've been analysing the mistakes this week. There's no reason to raise your voice when you know you didn't do well.

"The players must transform their disappointment into energy for tomorrow's game.

"I am not worried, we had won 11 games out of 13. It was normal to have a drop; unfortunately, we had it in a decisive moment after many games.

"It's normal not to be always focused when you play 15 games in 40 days – it's like we played half of a season in one month and a half.

"We knew it would be an intense season, we are here and we must fight for our targets."

Next opponents Crotone sit rock bottom of Serie A, with just three wins from their 22 games so far, although they are unbeaten in their past two league matches against Juve.

While the strugglers have only once avoided defeat in three successive games against a single top-flight opponent, the Bianconeri have failed to win four of their past seven league meetings with promoted sides.

"It's an important game to continue our path in the title race. It's going to be a tough game because Crotone are not going through a good moment, but they play well," Pirlo added.

"They've kept their philosophy and they are trying to impose themselves in every game."

Cristiano Ronaldo has not scored since February 6 but will look to make Crotone the 78th different side he has netted against in Europe's 'top five' league; only Zlatan Ibrahimovic (79) has scored against more such individual opponents since 2000.

Ronaldo has netted against each of the 17 current Serie A teams he has faced in so far, yet Pirlo said the former Real Madrid superstar is still working hard to improve his free-kick taking.

Since his arrival at Juve in 2018, Ronaldo has attempted 44 shots directly from free-kicks in the league but scored only once.

"Free-kick goals are important, they can decide games, especially against teams that sit deep," Pirlo said.

"Ronaldo is training well and is improving. He is calm and he is convinced he is soon going to score from a free-kick."
