Before Tuesday night’s rain-sodden League Cup expedition to Derby, it’s fair to say Chelsea’s fans had not really warmed to left-back Filipe Luis.

After all, Jose Mourinho has always preferred to play Cesar Azpilicueta in that position, even if ‘Dave’ – as team-mates call the full back – has not naturally gravitated to that position.

But Luis’ dazzling free kick, earned by the softest of fouls on Didier Drogba, proved the most inspiring moment of the Blues’ 3-1 victory at the iPro stadium, and could be the turning point in Luis’ relationship with the Stamford Bridge faithful.

It’s not as if the Brazilian, signed from Atletico Madrid, has taken time to settle… it’s just that he’s been overlooked because of Jose’s admiration for Azpilicueta.

The free kick at Derby was all the more remarkable because half a dozen other Chelsea players were circling 30 yards out, wanting to have a punt.

But Luis stood firm, captain John Terry gave him the nod, and the ball curled past Lee Grant.

Eden Hazard and Andre Schurrle were also on target for the Blues; the Hazard goal a further demonstration of his growing maturity… and value to Chelsea’s title hunt.

But Luis is a rarity.

The 29-year-old is a serious thinker and able mentor to younger players. Insiders speak of his future management potential, especially as his knowledge straddles European and South American football (he spend a season at Ajax, observing if not playing competitively).

He speaks fluent English, and loves London… spending time with samba boys Willian and Oscar at their Fulham homes, round the corner from Craven Cottage.

Luis, who recently became a dad for the second time, learnt English by mimicking actors on films on TV. Thank goodness he preferred Sound of Music to Reservoir Dogs.

Next up for Chelsea, a Monday night trip to Stoke. Double shinpads will be needed as the Potters will be aiming to give the Blues a hearty northern welcome.
