PHOTOS: Costa does a 'Balotelli' in Chelsea training

We compile the best photos from Chelsea's training session ahead of their Champions League match against Schalke tomorrow.

Diego Costa may have proven a natural at finding the back of the net since moving the Chelsea this summer, but he is not such a master at putting a bib on. 

The Brazilian born striker had to be helped out by Mohamed Salah in training today, as he struggled to fit his arm in the garment. 

It is a similar problem to the one which Liverpool striker Mario Balotelli famously had while playing for Manchester City a few years ago. 

Chelsea trained today, as they prepare to face Schalke in the Champions League. 

The Blues travel to Germany knowing that a win would see them qualify for the knockout stages and they will be determined to get the three points, as a result.

Jose Mourinho's men are the heavy favourites to grab the three points, but they didn't look under pressure today as they enjoyed a jovial training session. 

Here is the best pictures from Chelsea training earlier this morning.
