Norwich’s hopes of staying in the Premier League remain alive after they dented Chelsea’s title ambitions with a hard-fought draw at Stamford Bridge.
The best chances fell to a dominant Chelsea, with John Terry going close with a header and Andre Schurrle hitting the post in the first half.
But City’s Martin Olsson had a strong penalty appeal turned down early on.
Chelsea, monopolising possession, once again hit the woodwork after the break with David Luiz the man denied.
Victory would have moved Chelsea to the top of the table.
