The Portuguese defender joined Arsenal in the summer to provide as a backup for Kieran Tierney.
He has been making some horrendous performances in the absence of first-choice Kieran Tierney.
He is just 22 and is expected to deliver some top performances immediately on the go.
Club legend Ray Parlour believes Spurs will have an easy outlet with Tavares on the left side.
Parlour tells TalkSport: “I worry about the full-back areas.
“Tierney is brilliant if he stays fit. He’s been injured quite often in an Arsenal shirt.
Defensively, he’s (Tavares) not the best if I’m being honest. He’s got to improve on that.
“He’s better in a three at the back, when he plays wing-back. But he’s vulnerable at left-back.
“And I’m sure Spurs will be saying; ‘Well OK, let’s play down the left-hand side and Tavares.’
“They might get a bit of joy down that side when they play them next Thursday.”
