Fabio Capello knows a thing or two about English football - having managed the England national team for a four-year spell before resigning in February 2012.
And it seems that the Italian is still fondly following the Premier League, after spending several years watching league action from executive boxes up and down the country, during his time as Three Lions boss.
It's safe to say that the 70-year-old could make a fair judgement about teams in England, based on his experience, and it seems the Italian has been hugely impressed with one club in particular this season.

As per the Mirror, Capello used just one word to describe Jurgen Klopp's Liverpool side, that currently tops the Premier League table with 26 points from 11 games and sit a point and a place above Chelsea.
A shock 2-0 loss to Burnley is the only blemish on what has otherwise been a fine start to the campaign for the Reds, who are also in the quarter-finals of the League Cup.
“Liverpool are spectacular." Capello admitted. "What is not known is how long it will last."
The former Real Madrid coach, though, is not sure whether Klopp's men can keep up their impressive form for the remaining two thirds of the campaign, with their current defensive frailties.
Liverpool have already conceded 14 goals in 11 league games this campaign, but boast a phenomenal 30 goals scored in those fixtures, also.
While the Reds may be leaking goals, Capello believes the defensive solidity of Chelsea will continue for the rest of the season and could see his compatriot Antonio Conte lift the Premier League title in his first season in charge.
The Blues have conceded just nine times this campaign, with three of those being shipped away to London rivals Arsenal, and clearly Conte's early-season fears over the strength and depth of his defence have been allayed.
Conte's resilient Blues
"Chelsea are solid." Capello added. "Conte is working well. To score against Chelsea is really difficult. For me that can happen until the end."
However, while Capello has been impressed with the Premier League's current top two, both clubs are well aware that there will be many twists and turns to come in a long and demanding campaign.
Manchester City already look a serious force under Pep Guardiola, while Arsenal and Tottenham will be hoping that their promising starts to the season can continue, and that they can close the gap on Liverpool and Chelsea.
