West Ham United will be looking to continue their cracking Premier League run going when they take on Spurs on Sunday.
The Irons go into the game on the back of impressive comprehensive victories against Wolves and Leicester City.
David Moyes was working from isolation for both of those games, and he will have been delighted with the defensive work from his side.
Vladimir Coufal took massive plaudits for his performance in his debut against Leicester, and it won’t get any easier for the Czech defender on Sunday.
The 28-year-old made three tackles and won two of his aerial battles as he helped keep another massive clean sheet according to WhoScored.
It doesn’t get any easier for the defender though, with next up a massive test against Spurs key man Heung-Min Son.
The Korean superstar has started the season phenomenally, scoring six goals and delivering a single assist in a deadly partnership with Harry Kane.
What does Coufal have to look out for?
Son may start out wide on the left, but he loves to drift in-behind and penetrate defences, and he must stop that run behind his fellow defenders.
Son tormented Manchester United with his pace, but as you can see in this screenshot, the likes of Eric Bailly and Arron Wan-Bissaka are ball-watching.
If Coufal keeps his attention on the man rather than the ball, he should be able to make sure that Son can’t drift into space as easily as he has this season against others.
Communication with his fellow defenders and keeping a good line could also see Son drift offside very easily, a weapon that the Hammers and Coufal must learn from Southampton’s previous mistakes.
Despite looking across the line, Kyle Walker-Peters still attempts to play Son offside, and Coufal can eliminate this by organising his defence and staying goal side.
Yes, this is Coufal’s biggest test yet, but should the 28-year-old stay disciplined, there is no reason why he can’t keep the Korean quiet.
