Chelsea are chasing Republic of Ireland starlet Elvis Azah.
The Daily Mail says Celtic are interested in signing Azah after he impressed in a trial match.
The 16-year-old winger scored one goal and created another for Celtic's youth team in a 4-1 win over Partick Thistle earlier this week.
Chelsea are also monitoring Azah, while Southampton and Brighton have also expressed an interest in the youngster.
He was born in Ghana to Ghanaian parents but moved to Ireland with his mother at the age of 11 and recently received his Irish citizenship.
Azah, who can play on the wing or further forward in attack, has previously had trials at Manchester United and Everton.
However, they couldn't sign the youngster because he didn't have Irish citizenship at the time.
