Why Chelsea need more than a new goalkeeper to be title challengers

Despite making only one error leading to a goal last season, compared with three by Martinez at Villa, Sanchez is now considered available for transfer and has fallen to fourth in the goalkeeping pecking order at Stamford Bridge.

There was little blame attached to the goalkeeper for any of the three goals conceded in their 4-3 victory, unlike on Monday, when Robert Sanchez was clearly at fault for the first goal, and arguably the second, in Chelsea's 3-2 win at Fulham." Ex-Premier League goalkeeper Shay Given, who is a pundit on Sunday's Match of the Day, described Martinez as a "brilliant signing".
