Danny Mills says that he is not convinced Wolves defender Willy Boly is good enough to be playing for a top-four side as Tottenham plot transfer missions over a potential deal.

The former Manchester CIty and England full-back, speaking exclusively to Football Insider assistant editor Russell Edge, says that the French powerhouse has looked “erratic” at times this season and that he is not sure whether he is ready for the step up.

As revealed by Football Insider, Spurs are set to keep a close eye on the French powerhouse with a number of scouting missions over the next couple of months as they weigh up launching a move to sign the centre back.

Despite being a mainstay for Nuno Espirito Santo during the club’s impressive first season back in the Premier League, Mills says that he has not seen enough from the 28-year-old to suggest he is a top-four quality defender.

Mills told Football Insider: “I look at Boly and yes, he had a decent season last season, but I’m not 100 per cent convinced he’s ready for the step up to top-four and Champions League football.

“Of late, in the early part of the season, he’s made one or two errors, been a little bit erratic at times with some of those decisions. Is he good enough to go into the Tottenham side? I suppose if you’re going to lose Vertonghen or Alderweireld, he could play alongside Sanchez perhaps.

“I haven’t looked at Boly and thought he goes into one of the top four sides. He’s done very, very well for Wolves but I haven’t seen him and gone: ‘Oh wow.'”

Boly played in all but two of Wolves’ Premier League games last season as the newly-promoted outfit earned a place in this term’s Europa League qualifiers.

He has continued to be a regular in the starting XI at Molineux, with 14 appearances under his belt already across all competitions.
