The North Londoners started their 2020/2021 season with a shocking defeat at the hands of Everton in the Premier League last weekend, putting up a toothless and lethargic display at the Tottenham Hotspur stadium.
Tottenham Hotspur face Bulgarian side Lokomotiv Plovdiv in a Europa League qualifier on Thursday, after they could only secure a sixth-place finish in the Premier League last season.
Spurs have already confirmed the signing of Matt Doherty and are on the verge of re-signing Gareth Bale from Real Madrid.
The Premier League side are also mulling over the possibility of securing the services of Sergio Reguilon from Los Blancos.
O’Hara believes Mourinho faces a bigger challenge as he thinks the squad lack desire and commitment to play at the top level.
"They look like a bunch of spoiled kids! Get some leaders and characters in the camp and pull your fingers out - this is Spurs Football Club you are playing for," O'Hara told talkSPORT.
“You go through that team: Davies, average; Alderweireld, average; Dier, below average; Doherty, just signed, decent; Hojbjerg, average; Winks, decent; Alli, average; Son, brilliant; Kane, brilliant; Lucas Moura, touch and go.
“We need centre-backs with pace. We’ve just signed Matt Doherty from Wolves who has been playing wing-back for years; he’s not a right-back, he’s a wing-back.
“So if you are going to play him that high up the pitch you need two centre-halves who are very, very quick and very, very good one-on-one defenders, because they are going to get left exposed.
“You need to squeeze up the pitch and be brave and press high up. If they get done in behind or done over the top, that’s on me – I’m the gaffer.
“But I guarantee over the course of a season you will condense a pitch enough to win the ball back more in high areas and be closer together so you’ll be able to control football matches.
“They are so stretched, it’s unbelievable. I mean, anyone could play against Spurs!"
