The Portuguese defender could do worse than to take his own advice on board after enduring arguably the most difficult test of his short Rangers career at Firhill.
Needless to say, the Scottish game is a different proposition to the slower paced Portuguese top flight, where Cardoso represented Vitoria Setubal before securing a summer move to Ibrox for around £1.3 million (Daily Record).
And, despite standing over 6ft, it is clear that Cardoso could do with adding some meat to his bones. After all, he was given a torrid time by rambunctious Partick forward Miles Storey on Friday, the striker dominating his defensive opponent with sharp movement and fearsome physicality.
Storey had a hand in both goals and Cardoso hardly looked like the upgrade Rangers had hoped for when they signed him this summer.
There is no doubting that the former Benfica youngster has talent, his reading of the game is impressive and he holds plenty of promise in the air. However, Cardoso will come up against no shortage of physical centre-forwards in Scotland and must find a way to combat their strengths. The draw against Partick is a learning curve rather than a cause for alarm, however.
As was his shaky display in the 3-2 home defeat to Hibernian last month.
But if Rangers are to avoid dropping points against the likes of Partick and newly promoted Hibs, they need their backline to able to withstand the pressure.
