The West Ham boss has been discussing the 22-year-old right-back after he signed from Leeds.
Slaven Bilic has been impressed with 'confident' Sam Byram after his first training sessions as a West Ham United player, according to his regular column in the London Evening Standard.
The youngster left Leeds United for West Ham this week and Bilic has formed a good first impression of the right-sided defender & midfielder.
And the Hammers boss is also happy with Byram's versatility.
The Croat told the Standard: "Sam seems a confident lad and is a good player. Of course, at his age, he has room to improve every aspect of his game.
"He has that potential and is showing his quality by playing for Leeds in more than one position."
Byram's versatility is an interesting point indeed as, despite his main position being at right-back, the 22-year-old ha often shone on the right of midfield.
That was especially the case last season. Under Neil Redfearn, Byram would show defensive weaknesses but thrive going forward, which naturally prompted a move further up the pitch.
For West Ham, of course, the youngster will be ideal as a right-back. Carl Jenkinson's form has left plenty to be desired and he will likely now return to Arsenal once his loan spell comes to an end.
But former Leeds man Byram can be equally as effective further forward as he is at right-back - and him raiding down the opposite flank to Aaron Cresswell is an exciting prospect.
