Such seems to be the case for one Spanish midfielder who has been long under the radar of several European powerhouses, particularly that of Manchester United.
Shaw has struggled for form and fitness at United, and nearly had his career ended after suffering a horrific double-leg break in 2015. Tuesday night was just a glimpse of what Shaw can do.
Before kick-off, the BT Sport panel of Paul Scholes, Steven Gerrard and Rio Ferdinand discussed Shaw's time at United and came out with some very interesting observations.
Shaw was praised by Jose Mourinho who admitted surprise at his performance.
The resurgence of Ashley Young has also not helped his cause, with the 32-year-old excelling on the left-hand side of defence and he was rightly up for the Premier League Player of the Month, which was eventually won by Liverpool's Mohamed Salah. However, it is clear he is not the long-term answer in the position for Mourinho.
Mourinho had no concerns about the defender suffering cramp late in the game. He certainly took his opportunity well and on another day he could have ended the game with a goal and assist, getting a chance himself in the 20 minute and providing both Romelu Lukaku and Marcus Rashford with chances both should have done better with. A couple of years ago, I thought we were signing the best left back in the world'.
The England global had played only 48 minutes of EFL Cup football this season - both of which came from the bench. The player has a lot to show to Mourinho to convince the Portuguese manager. "Especially with the ball going forward, really risky, creating a lot, great intensity in his game, no surprise in minute 80 he is feeling the consequences of that intensity".
"He was waiting for quite a long time, he was deserving [of his chance] for quite a long time".
