Chelsea have invited Northern Ireland teenager Charlie Allen for trials.

The Daily Express says the 15-year-old has already broken into the first team at Northern Irish champions Linfield, and is now being chased by a bevy of Premier League clubs, having had trials at Tottenham and Manchester City.

Chelsea, currently under a transfer ban, are exploring the possibility of taking Allen on trial. Norwich and Glaswegian giants Rangers are also, though, on the teenager's trail.

Attacking midfielder Allen made his senior debut during the latter stages of last season, playing the final eight minutes of a 1-1 draw at Coleraine to become the club's youngest debutant, as Linfield closed on the Danske Bank Premiership title.
