Tony Adams has been growing increasingly frustrated with Arsenal, the way they're playing, and the club's recruitment over the past few years.
Speaking on Premier League Productions, the former Arsenal defender took it out on Hector Bellerin, who he believes is not playing the way he should.
He saw Bellerin heading up the field too much when he was needed in defence against Tottenham on Sunday, and thinks Arsenal could've avoided their first goal if he played more defensively.
'Work with him' said Adams. 'Don't get him on the right wing, say "sit there" and go out there morning and afternoon with the kid and make him into a full back.'
However, Adams said that there is also potential for Bellerin to become a great player, comparing him to another club legend.
'He's no better or no worse than Lee Dixon when he came to the club. He was playing like a right winger.
'I went "Dicko, come here. Sit here. Learn your job. First and foremost stop that ball going in the back of the net.'
Tottenham broke quickly for their first goal against Arsenal, with Harry Kane playing the ball through to Son Heung-min who then fired excellently into the net from range.
'Where was Hector when that first goal was going in? He's up the pitch. Do your job first. Learn how to be a good defender, keep clean sheets, then take it from there.'
Spurs got another goal on the break later in the half, and then held onto their lead despite a lot of Arsenal possession in the second half.
Jose Mourinho's men are now top of the table, ahead of Liverpool on goal difference, even though the Reds got a 4-0 win later on Sunday.
