When Sven-Göran Eriksson took a 17-year-old Theo Walcott to The World Cup in 2006, many predicted great things for the talented young speedster.
It is unfathomable to think he has only participated in one other major tournament since then - Euro 2012.
As we approach Euro 2016, there is a real possibility Theo could again miss out, and this time not because of injury.
He is out of form and low on confidence, and with games coming up against Germany and Holland, there will be no hiding place.
He has scored only nine goals from 38 appearances for Arsenal this season, along with six assists.
Neither of those returns are good enough, whether he is an out-and-out striker, or a right winger.
His season was summed up, when Arsenal turned up to Everton on Saturday, in what was a must-win game.
Just like in midweek against Barcelona, he was left on the bench and watched on as 19-year-old Alex Iwobi stole his place and the show with an efficient, decisive display. Unlike in the Nou Camp, at Goodison Park he remained on the sidelines for the full 90 minutess.
He will be thanking himself lucky that Alex Oxlade-Chamberlain and Raheem Sterling are absent from the England squad. They will return before the end of the season though, and Theo will be hoping that so too, will his form.
