2. Alex Oxlade-Chamberlain- 18 years & 184 days
Liverpool attacking midfielder Alex Oxlade-Chamberlain is still recovering from a terrible ACL injury he sustained at the end of last season. The former Arsenal star will certainly push himself harder to be available for selection before the end of the season. In Europe, he is only the second youngest English player to play in the knockout stage aged 18 years and 184 days.

Former Arsenal star Theo Walcott is now trying to resurrect his career at Everton after years of poor show at Emirates Stadium. England forward is also trying to impress England boss Gareth Southgate. He also holds a special record that will be hard to break. The former Southampton man is the youngest English star ever to play in UEFA Champions League knockout stage. He did so for the Gunners when he was only 17 years and 356 days.
