Juan Sebastian Veron always doubts whether Inter can win a game and thinks they need to be more clinical like Juventus, who he never feels will lose.

Inter will leapfrog local rivals Milan and go top of Serie A on Sunday if they defeat Juve in a league game for the first time since September 2016, having drawn two and lost five of their past seven matches.

Andrea Pirlo's side sit four points behind the Nerazzurri but possess a game in hand, so following up their victory over Milan in their previous away league game would put them firmly back in the title race.

However, they have not beaten both Inter and Milan away from home in the first half of a Serie A season since 1930-31.

Former Inter midfielder Veron acknowledged that Juve are not playing at the same level that has seen them win nine straight Scudetti, but he believes they still have a killer edge that is missing in Antonio Conte's team.

"I follow Juve a little bit. I follow Inter more. Juventus must find again what they got in the past years. They felt unbeatable," Veron told Stats Perform News.

"Keeping the same level for many years is very hard. Juve did it. Perhaps this year things haven't gone as they wanted.

"On the other side, Inter have responsibilities. They are looking for the best way to be a great team again. It's not easy. They must find consistency in their results and their football. They must play in the right way.

"When you watch Juve, you know they will win. When you watch Inter, you know it's 50-50. They need to be decisive to gain results."

He added: "For me, the first thing about this match is the morale boost it can mean. That's for sure. After that, you play for points that are important as well.

"But [for Inter] being able to win after a long time would be, for a team who needs victories, important for the title race. For me, it's the most important thing for them."

Veron won the 2005-06 Serie A title - awarded due to Juve's involvement in the Calciopoli scandal - and the Coppa Italia twice during his two seasons on loan at Inter from Chelsea, but the club have not lifted any silverware since 2010-11.

Conte has come under pressure after failing to end that wait in his first campaign at the helm and Veron thinks the coach could use some stronger personalities in his squad.

"It is normal that [Conte] feels pressure from fans who want to win. The club signed stronger players, but it is not so easy to be consistent. You must gain results to get the right winning mentality," said Veron.

"Perhaps they need a player with a strong personality. You asked me for some names [from Inter's past for today], I could have told you three or 10. But today's football is different because of the money.

"It depends on clubs' strategies. In clubs like Inter you need to be used to pressure. In the end, the solution is to build the right team able to handle the pressure. But it takes time."
