Spurs failed to get into gear until changes were made against Everton.
Tottenham manager Mauricio Pochettino
The manner of last weekend’s draw with Everton has presented Mauricio Pochettino with something of a selection headache ahead of Saturday’s clash with Crystal Palace.

Both are powerful defensive midfielders, who’s strengths lie in winning back possession and playing the ball simply.
But Pochettino’s system requires one anchorman who can drop between the centre-backs and a forward-thinking box-to-box presence beside him.
Neither Dier or Wanyama are capable of playing that box-to-box role and Tottenham’s attacking threat was severely limited whilst they were both on the pitch.

Spurs improved massively and were unlucky not to go on and claim all three points, leaving Pochettino with a major decision ahead of the Eagles’ trip to White Hart Lane this weekend.
Janssen’s excellent showing will have placed him in contention for a start but more critical is the issue of how the midfield pivot changes.

Eriksen has proven he can play in a deeper role and Dele Alli was originally seen as a box-to-box midfielder before his move to the Lane.

Pochettino would of course have to drop one of Dier or Wanyama to make way and his decision to keep the latter on for the full 90 minutes against Everton could be a good indication of how he is leaning.
Spurs will be determined to claim three points this weekend and after seeing how a change in approach affected his team on Saturday, Pochettino must make the necessary adjustments for the Palace clash.
