Former Newcastle United man Peter Lovenkrands believes Daryl Janmaat needs to stop committing 'silly' challenges or he could end up costing Alan Pardew's side dearly.
One tackle in particular during Newcastle's Capital One Cup win over Crystal Palace left Lovenkrands fuming as it ended up costing the Magpies a goal.
And the former Premier League striker says Janmaat, who was brought to St James' Park for a reported fee of £5 million this summer, needs to cut such incidents out of his game or risk losing his side points in the top flight.
"The first goal for Crystal Palace was a silly, silly challenge from Daryl Janmaat," Lovenkrands wrote in his column for the Newcastle Evening Chronicle.
"For me, in that situation why would you go diving in to kick a ball away from somebody who is heading towards the byline? Wilfried Zaha was going nowhere.
"Silly things like that at this level cost you dearly or costing you the game.
"Yes there were three goals at the other end which won the game. But in the narrower defeats things like Janmaat’s challenge cost you games, in the Premier League they cost you points.
"Top defenders should not be diving in for situations like that one. Just run next to him and make sure he doesn’t get across – that’s all you can do. Things like that are negative to see."
Pardew's men travel to Stoke City on Monday night for their sixth league game of the season but are still in search of their first win of the Premier League campaign.
