Brentford boss Mark Warburton admits Arsenal midfielder Jon Toral has given him a selection headache.
The young Gunner has yet to start a league game for the Bees since joining on loan in the summer, but has featured five times off the bench.
Toral has staked his claim for more game time after impressing in training and Warburton admits the 19-year-old was unfortunate not to feature from the off in Tuesday night's stalemate with Sheffield Wednesday.
He said: "Jon Toral has been outstanding in training and I contemplated starting him.
"He's working great and getting better, fitter and stronger. He's recognising his work off the ball because at this level you get punished if you don't do your job.
"On the ball I've got no doubts about his quality."
