Bruno Lage believes the gap Liverpool and Manchester City have created in the Premier League could take 10 years to fill.
Lage takes Wolves to Anfield on Sunday knowing City must slip up against Aston Villa if Liverpool are going to overhaul them to win the title.
But the top two are 18 and 19 points ahead of Chelsea in third place.
'City finished third in their first year with Pep (2016-17), so it takes time to build that kind of team,' said Lage.
