I think supporters roundly boo'ing the team during and after games might have a negative impact on the desire of potential incoming players to sign with us. That's assuming we're actually looking to bring in any players before the window closes which may not be the case. But yeah, if you were Gary Cahill and had two identical offers sitting there - Arsenal and someone else - and you've been watching Arsenal get boo'ed every week, would you not more readily choose the other club, all things being equal.
