Yeşil only recently recovered from a double cruciate ligament injury that has seen him spend most of the season on the sidelines.
The former Bayer Leverkusen man got his name on the scoresheet for the second game in a row but was unable to prevent the 2-1 loss against Fleetwood Town at Kirby academy last week.
“We absolutely deserve to win it because we have so many young players in our squad, maybe we are the youngest squad in the U21 Premier League”,the Germany youth international told LiverpoolFC.com.
“We played so many games [well] and were sometimes a little unlucky with the result but I’m sure if we win all four games we will get there.”
Yeşil has four goals in seven U21 appearances for the Reds this season.
