Unai Emery has exposed the player in his team that has given him selection headache so far, since arriving at the club in the summer.
Emery who named Lucas Torreira as the player who has given him the sleepless night on who to start ahead of the other.
While noting that he is pleased with all his players who have all been working hard in the past few weeks, the Spanish manager pointed at Torreira as an exciting player and a good prospect.
The edgy beginning of his reign at Arsenal with two consecutive defeats to Manchester City and Chelsea respectively has not put away smile from the eyes of the former PSG manager whenever he sees his players.
Torreira is, however, yet to be named in the starting lineup of the Arsenal team but his impact for the team each time giving an opportunity caught the eye of both fans and pundits.
His continuous exclusion from the starting eleven has therefore been a surprise to many as he has been tipped to provide the steel cover for the defence, a quality that has been missing for Arsenal in the past years.
Emery has therefore confirmed that the Chilean has the quality to break through to the starting lineup in successive fixtures.
