Debuchy is a quality player. Getting rid of a 31 year old RB just to turn around and sign a 29 year old RB is bizarre though. We'll need to replace him in two years, three at most. This was a good opportunity to lock down this position for many years to come but it looks like we're going to buy more time for Jenkinson and Bellerin. I hope they make the most of it. In the immediate short term, this would be a very good signing.
