Tony Pulis warned Manchester City that there is still a long way to go in the title race and plenty of obstacles to clear in the months ahead.
Pep Guardiola's side clinched their eighth Premier League win in a row at the Hawthorns to restore a five-point lead over Manchester United at the top of the table.
But Pulis believes that United's shock defeat at Huddersfield last weekend demonstrated the hidden dangers that could yet derail City's bid as they continue to challenge in four competitions.
'There are a lot of things they have to overcome,' said the West Brom boss.
