Hansi Flick says his Barcelona team must play with “greater aggression” now that it finds itself in a Champions League mini-slump.

If it is possible for a player to fly under the radar when they cost €34million (£28.7m, $36.9m), Estevao managed it by arriving at Stamford Bridge in the same summer as Joao Pedro (£50 from Brighton), Jamie Gittens (£48.5m from Borussia Dortmund), Alejandro Garnacho (£40million from Manchester United) and Liam Delap (£30million from Ipswich).

Chelsea secured a convincing 3-0 Champions League win over Barcelona on Tuesday, as Estevao proved himself once again on the big stage.

For instance, you may recall this column's belief that the league phase was going to begin in quite disastrous fashion for Atletico Madrid, who had the look of yesterday's team going into this competition.

There is a tradition in the recent history of modern Barcelona of brilliant players coming to Stamford Bridge and delivering something spectacular, although on this Champions League night that honour belonged to Chelsea’s own teenage sensation.

On a night when Chelsea dominated and convincingly defeated Barcelona, 18-year-old star Estêvão was the standout performer, scrawling his name across the history books by scoring his third goal in as many Champions League starts.
