Fabio Capello is the latest manager to laud Chelsea boss Thomas Tuchel but he isn't the only person to be gushing over the German right now.
The Blues' 4-0 thumping of Juventus at Stamford Bridge on Tuesday night was the ex-Borussia Dortmund and Paris Saint-Germain coach's 50th game in charge in west London.
Tuchel took over from club legend Frank Lampard in January this year, with the Blues sat ninth in the Premier League table at the time of their club legend's departure.

But Tuchel's time in charge has been nothing short of a resounding success, with him masterminding their recovery to finish in the top four last term before leading the club to their second Champions League title.
The UEFA Super Cup success then preceded a stunning start to the current campaign which sees Chelsea sit three points clear at the top of the table and well in contention for a sixth Premier League title come May.
Meanwhile, Tuesday night's drubbing of Serie A giants Juventus saw the Blues continue their defence of their European crown by qualifying for the last 16, and they also face a League Cup quarter-final against Brentford next month.
So just what do the statistics show about just how well Tuchel, 48, has done in his first job in England?
Well, Tuesday's win - which came courtesy of goals from Trevor Chalobah, Callum Hudson-Odoi, Reece James and Timo Werner - was the German's 32nd win in charge of the west London outfit.

The wins at home and away from Stamford Bridge are split equally at 15 each, while beating Man City at Wembley in the FA Cup semi-final and in Porto in the Champions League final last season were the two victories gained on neutral territory.
His 18 other matches in charge have ended in 11 draws and just seven defeats, the most recent of which came in the reverse fixture against Juventus at the end of September, four days on from their home defeat by Man City.
Their defeat against Pep Guardiola's men was the fourth reverse on home soil under Tuchel, with West Brom, Porto and Arsenal also winning at Stamford Bridge last season.
Their FA Cup final defeat by Leicester, meanwhile, was the only loss at a neutral venue, while away trips at Aston Villa last term on the final day of the season and Juventus this season constitute the other reverses.
His players have scored a remarkable 81 goals since Tuchel replaced Frank Lampard as boss
Tuesday's win against the Serie A giants saw revenge claimed and four goals scored without reply, but it was the 7-0 hammering of Norwich at the end of last month which constitutes their biggest win under their German boss.
By contrast, the shock 5-2 home reverse against West Brom - who were relegated at the end of last season - in April, which brought the 14-match unbeaten start to Tuchel's tenure to an end, remains the heaviest defeat under him.
The Blues are just four games away from matching that run, having extended their unbeaten streak to 10 games against Juventus, with fixtures against Manchester United, Watford, high-flying West Ham and Zenit St Petersburg to come.
But what has their form been like under Tuchel at both ends of the field? As you can imagine, 81 goals scored and only 24 goals conceded demonstrates the efficiency with which the Blues operate.
