Chelsea are transforming into a ‘machine’ this year.
The Blues are at the top of the Premier League table with Liverpool and Manchester United by their side.
Rio Ferdinand claims Tuchel has transformed the club into a machine since his takeover in January this year.
‘Chelsea are a concern if you’re trying to win the league,’ Ferdinand told the FIVE YouTube channel.
‘Any of the teams like Man Utd, Man City and Liverpool will be looking at Chelsea and thinking they look strong, they look solid, they look like they have weapons all over the pitch.
‘One of the biggest factors they are stingy, they don’t concede goals now. They’ve got the best clean sheet record since Tuchel took over in the whole league, they’ve got best defensive record in terms of goals conceded.
‘He’s making them a machine, they look like a team that can play ugly. They could be abymsal on the day then Lukaku will come up with two goals.
‘Yesterday [the 3-0 win against Aston Villa] he fed off two mistakes from Mings, fed off it. He’s now – I don’t care – he’s one of the best no.9s in the world, fact, no debating it.
‘You talk about Kane, Lewandowski, Ronaldo, Benzema, Lukaku is dancing in that ring with them. When he went to Serie A and you win the team there as the talisman you’re up there.
