London rivals Tottenham Hotspur and Chelsea meet at White Hart Lane on Sunday afternoon with the match-up between Eric Dier and Nemanja Matic sure to be vital in the final reckoning.

Tottenham's Dier has enjoyed an impressive start to the season. The 21-year-old has won rave reviews from all corners, earning himself a well deserved recent call-up to the England senior squad.

While at Chelsea, fellow defensive midfielder Matic has been identified as one of a handful of players at the club that are not performing to their best.

However, stats released by fantasy football game www.oulala.com reveal that the in-form Spurs midfielder still falls well short of the out-of-sorts Serbian.

The pair come head-to-head this weekend as Chelsea travel to White Hart Lane on Sunday in what will arguably be Dier's sternest challenge so far this season.

Oulala have analysed the stats from both players, revealing that the clash may not be as one sided as many would have expected.

Despite playing almost 200 minutes less than Dier this season, Matic has won more tackles (35 to 28), lost fewer (32 to 33) and has a better overall tackle success-rate than the 21-year-old (52 to 46 per cent).

The Serbian has also enjoyed a higher pass completion (89 to 85 per cent), has created more chances (11 to 4) and has won a higher percentage of overall duels (49 to 46 per cent).

Of the seven key criteria analysed, Dier leads for just two. The Spurs player has scored one more goal than Matic (2 to 1) and has made more interceptions (28 to 23).

Chelsea sit ten points and ten places adrift of Tottenham in the Premier League table ahead of Sunday's derby.

The battle between Dier and Matic looks to be key in deciding which side comes out on top.
