Some treatment and a good gym session this morning ?
Everton made a last-minute addition on transfer deadline day with the loan signing of Belgian teenager David Henen.
The 18-year-old had been training with the Toffees until recently but his parent club Anderlecht decided to sell him to Greek side Olympiakos on Monday.
However, Everton struck a deal to bring the youth international back to England for a season-long loan, although the paperwork was not completed until very late in the day.
