Former Chelsea goalkeeper Mark Schwarzer believes trouble is brewing at Stamford Bridge, telling talkSPORT ‘all the signs are there’ for implosion in the Blues dressing room.

Manager Antonio Conte impressed as he led Chelsea to the Premier League title in his first season in charge last term, however, the summer has been less than rosy for the Italian.

Conte has been unhappy with the club’s lack of top signings this summer and has openly spoken of the need for Chelsea to add players to the squad,

The Blues have secured the arrival of only three players so far, in Alvaro Morata (Real Madrid, £70m), Tiemoue Bakayoko (Monaco, £40m) and Antonio Rudiger (Roma, £31m), while there is still uncertainty surrounding the future of Diego Costa.

Conte cut a frustrated figure as his side suffered defeat to London rivals Arsenal in Sunday’s Community Shield game at Wembley Stadium – their second straight loss to the Gunners following their FA Cup final defeat last season.

And Schwarzer believes Chelsea could well erupt soon if the tension at the club continues to increase.

“All the signs are potentially there,” the Australian told the Alan Brazil Sports Breakfast.

“It all probably started in February when there were all those rumours about Costa wanting to leave and he could go to China.

“He was left out of the next squad and all of a sudden he reappeared as if nothing had happened, but I think under the surface there were always rumbles.

“Then come the summer, Costa comes out with the texts Conte sent him basically saying he can leave, and I think that was always going to cause problems.

“The longer this all goes on, there’s always going to be that destruction for Chelsea.

“Now, considering all the problems they’ve had with bringing players in, with players leaving and the Costa thing still hanging over the club – he would be an enormous loss and one that would cause a lot of problems for them when the season starts.

“They’ve had a lot of distractions and I think they could have moved on from all of this if they signed an adequate replacement.”
