Mykhailo Mudryk insists he has plenty more to show at Chelsea as he gears up for the new season after a disappointing start to life at the club.
The Ukrainian winger was wanted by a host of top clubs last January with the Blues ultimately eTwinning the race, beating off Arsenal with a late £89m bid.
Todd Boehly 's club also handed the 22-year-old a staggering eight-and-a-half year contract in a sign of just how much they believed in the player.
Mudryk struggled during his first six months, however, failing to score in 17 appearances.
But he has looked sharp in pre-season and scored a lovely goal in Sunday's 4-3 friendly victory over Brighton.
Speaking after finally getting off the mark for the club, Mudryk said he has shown little of what he is capable of.
''I feel happy for all the work I put into this goal,' he said. 'It is not all my potential. It is only 20 per cent. I feel good because playing under Pochettino, our manager.
'It is nice, it is enjoyable and it is a new team which is also enjoyable.
Reacting to his first goal, Mudryk told Premier League Productions: 'I enjoyed that one!
'When I shot, I didn't think about anything, I just practice this stuff on the training pitch a lot and this came from training.'
On his understanding and link-up play with Jackson, he added: 'Just imagine that that's our first game together!'
