Six Nations - Cueto: Ashton has been warned
Ashton became the first England player to score four tries in one Five or Six Nations match since 1914 as England routed†
Six years ago Cueto made a similar impact on international rugby - but his feast of eight tries in eight Tests soon turned to famine as defences got wise - and he said: "Teams start to target you and they will maybe throw extra defenders (at Ashton)."
He added: "Whenever you do your analysis on the teams you come up against you pick out the threats and without a shadow of a doubt, teams will be looking at Ashy.
"He has scored six tries in two games and is the out-and-out threat with England at the minute so he will be put under a lot of pressure."
But Cueto believes the unique way Ashton reads the game will still make him very difficult to stop.
"There is an art to what he does and it is unbelievable. He just anticipates everything," said Cueto.
"He will be tracking a play from 10 metres offside just in the hope that they will make a line-break and then he will be in that position.
"A lot of the times, if you are not offside, you are never going to be there.
"In the past, wingers have almost trailed the play from an onside position and if someone did make a line break, you are 10 metres behind the play and it is difficult to get there."
