Celtic will reportedly offer Robbie Keane another short-term deal if his proposed loan to Aston Villa doesn't occur.
The LA Galaxy striker is heading back to England to keep fit during winter with a training stint at former club Tottenham but it has emerged that Villa boss Alex McLeish is hoping to get him in on a two-month contract before the 2012 MLS season begins.
Just in case that falls through, Neil Lennon is likely to extend an invitation to the 32-year old Republic of Ireland captain who enjoyed a successful five-month spell at Parkhead in 2010, although it is believed Villa talks are at an advanced stage.
