Football: Five things we learned in Serie A

Footballers are not afraid to cry, Nikola Kalinic is a hat-trick hero, Higuain can't do it on his own, De Boer is on borrowed time, and goalline technology is not perfect.

Here are five things we learned in Serie A last weekend.

Locatelli is emotional, but happy
Italian footballers may have a reputation for the occasional theatrics, but when it comes to real-life emotions few have matched AC Milan midfielder Manuel Locatelli this season -- and he doesn't care who sees him. Locatelli hit the headlines two weeks ago when he scored a superb goal in a 4-3 win over Sassuolo and was so emotional at the end of the game that teammates had to help him regain composure as he wept uncontrollably in front of the television cameras. A 65th minute screamer by Locatelli on Saturday, when the San Siro hosted nearly 76,000 fans, beat legendary Juventus goalkeeper Gianluigi Buffon and earned a precious 1-0 win over the champions. Although the 18-year-old midfield ace kept the flow of tears to a trickle this time, he admitted: "The way I react is the way I react, and for me that's fine."

Kalinic the hat-trick hero
Croatia international Nikola Kalinic wowed most of Serie A with his goalscoring exploits for Fiorentina last season, when he notably hit a hat-trick in a 4-1 rout of Inter Milan. On Sunday, the gangly striker confirmed that was no fluke on his way to scoring his second hat-trick for La Viola in a 5-3 win at Cagliari that was generous to the Sardinians. Kalinic pulled La Viola level on 20 minutes after a perfect run behind the hosts' defence to send a glancing header past Marco Storari. After turning provider with a superb assist for Federico Bernardeschi, Kalinic fired an unstoppable curler past Storari then rose unchallenged to send a powerful header past Storari from 10 yards out.

Even with Higuain, Juve are not unbeatable
