Harry Kane, Christian Eriksen and Erik Lamela all hit the woodwork as we tried to see off the challenge of the Baggies but, after Craig Dawson's own goal in the first period, the Albion man scored at the right end with 18 minutes remaining to secure a share of the spoils for the visitors.
The result leaves Leicester City seven points ahead at the summit of the Premier League with only three games remaining.
