Sherwood clearly knows the three players well from his time in charge at White Hart Lane and will hope Mauricio Pochettino is looking to further trim his squad this summer.
The Argentine manager has already sold a number of under-performing talents and could be ready to allow others to leave as he seeks to re-shuffle his Tottenham pack.
Aston Villa are ready to offer £5m for pint-sized wide-man Lennon, some way below Tottenham’s £9m valuation, and one imagines it would take a higher fee to land Townsend.
Pochettino rarely used Townsend last season but the winger certainly impressed whilst on England national team duty and could be keen on a fresh challenge.
Meanwhile Aston Villa have seen their move for Adebayor collapse though Sherwood may well make a fresh move for the Togo international as he seeks to replace Christian Benteke.
