Chelsea are struggling with nerves as Premier League title rivals Tottenham close in, according to Shaun Wright-Phillips.
Sunday's 2-0 loss to Manchester United at Old Trafford coupled with Spurs' thumping 4-0 win over Bournemouth has seen the gap at the top close to four points.
With Chelsea 11 points clear less than two months ago, Wright-Phillips fears the players could be on a "downward spiral" while Tottenham crank up the pressure with seven consecutive wins.
"In a Premier League race it’s never over until it’s over," Shaun Wright-Phillips, speaking exclusively to 888sport, said.
"At one stage it was an 11 point gap and now it’s down to four points so that is nerve-wracking for the players. As we would say it’s squeaky bum time. It could be that they’re on a downward spiral.
"As big as the characters are in that dressing room I still think there will be a spell where they might get nervy if Tottenham keep going as they are."
The Premier League's top two meet at Wembley Stadium on Saturday for a place in the FA Cup final.
Antonio Conte is aiming to match fellow Italian Carlo Ancelotti's feat of winning the league and cup double in his first season - the club's sole double to date.
Wright-Phillips feels the achievement this season would better that of seven years ago.
He continued: "I think it would be the greatest double ever and I’d be especially delighted for Kante because of the amount of effort he puts into every game. He’s a delight to sit down and watch.
"Conte has done an outstanding job and they adapted to the formation change mid-season pretty quickly. They responded in exactly the way he’d have wanted."
