The 4 - 2 defeat of Chelsea by New York Red Bulls could be written off as a meaningless pre-season training session.
However, I detect there are problems in the camp and this result highlights some - but there are other tell tale signs.
Is Jose Mourinho losing his touch?

Well, Asmir Begovic certainly did last night - a couple of the Red Bull goals were calamitous goalkeeping errors.
The Chelsea defence was almost impregnable last season. They just don't give four goals away (only to Spurs and Bradford last season) and the opposition in this game was scrapping the bottom of the barrel material at best. Chelsea were expected to win by a cricket score.
Trouble on the horizon for Chelsea
Diego Costa, who only played the second half last night, made an amazing impact in the Premier League last season but when he was injured is was clear that there was no obvious stand in.
I also suspect Premier League defenders were getting wise to him. Didier Drogba was asked to fill the void but he was far too over the hill to make a worthwhile contribution. Few can argue it was ever worthwhile bringing him back into the team after he had effectively hung up his boots.
Going back to the goalkeeping department, it seemed crazy to let Petr Cech go. He's only 33 years old. Remember Brad Friedel is still playing at 43 years of age.
The purchase of Radamel Falcao, who disappointed the Old Trafford faithful time and time again, must be a huge gamble. He didn't play last night but few would think he would have made any impact if he had.
Last night's nightmare back-pass by John Terry proves he's also over the hill and needs replacing. I just can't see John Stones filling that gap even if Everton agree to selling him.
All these facts add up to the fact that all is not well at Stamford Bridge and Jose Mourinho has a great deal of work to do to stay as title contenders next season. If the Red Bull game doesn't prove it nothing else will.
