The 24 year old has long been tipped as a future star, but is yet to deliver on his tremendous potential, but as yet he has not quite fully fulfilled it.
He joined Chelsea from Everton in January 2018, but injury problems meant he only made two Premier League appearances for the 'Blues' in his first season.
However he has really begun to kick on this campaign and has made 11 appearances so far and is impressing under Maurizio Sarri, earning his international recall
Speaking in a press conference the midfielder said he had come back a more mature player and was excited to return to England duty:
''I'm over the moon to be back, I feel like it's been a long time coming but I feel like I have worked hard over the last couple of years and that it's fully deserved that I am back here.''
'I feel like I have matured as a person and understood what football is, and taken little details on as I have done now under the manager (Sarri).
'Things are going really well for me now and I'm fully focused on improving and kicking on.'
He missed out on a place in the squad for this summer's World Cup but he said he enjoyed watching his team-mates reach the semi-finals.
'I was proud to see the lads do really well and see how proud the country was of the boys.
'After where I was at, I had had a difficult season through injuries and I had a few niggles but kept a positive mind. I had a strong pre-season and things are going well for me now.'
