Ahead of Wednesday's North London derby duel, there is much for Tottenham Hotspur boss Mauricio Pochettino to ponder, but few dilemmas will be greater than deciding whether or not to include Ryan Mason in his starting line-up.
Mason has sat out Spurs' last two fixtures, against Qarabag and Crystal Palace, after injuring himself at Sunderland a fortnight ago.
However, the central midfielder could, as covered by the International Business Times, be available for selection against Arsenal, and Pochettino faces a tricky decision over whether to use him or not.
Mason was one of Spurs’ form players over the early part of the season, but in his absence Dele Alli has stepped up to the plate.
The 18-year-old formed an excellent partnership with Eric Dier in the heart of Tottenham's midfield against Palace at the weekend, and displacing him after that display would be harsh.
However, if ever there was a player built for a match against Arsenal, it is Mason. The 23-year-old understands the fixture, having grown up in Spurs' academy, and is a player who thrives off a physical battle.
It leaves Pochettino with a tough choice, as the risk element surrounding Mason's fitness must also be taken into account, but one which highlights the quality that he now possesses in his squad following a productive summer of recruitment.
If he does opt to use Alli, then the midfielder is likely to offer drive and creativity, but if he goes with Mason, he may have slightly more energy in the centre of the pitch - and greater defensive solidarity.
Whoever Pochettino picks, it is a decision that he must get right, as if Spurs are to beat Arsenal, they will need their two defensive midfielders to set the tone for their performance.
