Arsenal and Arteta finished last season on a high, beating Chelsea to win the FA Cup, but the Spaniard is under increasing pressure after a pair of defeats and a draw in the side’s last three Premier League matches.
Top-of-the-table Spurs are already eight points better off than the Gunners – who are languishing down in 14th place – and Jose Mourinho’s men will be confident of victory at the Tottenham Hotspur Stadium, with Harry Kane and Son Heung-min firing on all cylinders.
But Dier stressed the clubs’ position in the table was ‘irrelevant’ at such an early stage of the campaign and expects a ‘great game’ between the two bitter rivals on Sunday afternoon.
‘They’re going through a bit of a difficult period but in these games it doesn’t really matter, who is where in the table is irrelevant,’ the Tottenham defender told Sky Sports.
‘We know how much of a difficult game it’s going to be, how much the game means for us as players and for the fanbase and the club.
‘The position in the table is irrelevant and I think it’s very early on in the season for both teams.
‘It’s going to be a great game either way and one we’re really looking forward to.’
The England international insisted Arsenal were in ‘good hands’ despite their poor run of results under Arteta in recent weeks.
Asked whether Arsenal’s results are likely to improve, Dier replied: ‘Yeah, of course.
‘They’ve got a lot of quality in their team and I think they’ve got a very exciting young manager.
‘I think he’s maybe the most – personally, obviously I’m not on the inside! – but from what I see, the most exciting young manager in Europe, for sure.
‘We know they have a lot of quality in their squad and we’ll be very aware of that on Sunday.’
