Two teams from London with two very different aims. Welcome from Stamford Bridge as Liam Rosenior's Chelsea take on Nuno Espirito Santo's West Ham in tonight's London derby.
It's been a month of London derbies for the hosts, with this being their sixth in January alone. They have come out on top in their last two in the Premier League, and off the back of a massive Champions League win over Napoli, the Blues will be feeling good going into this one.
As for the Hammers, things aren't looking so pretty as they still sit in the bottom three. But, off the back of a trio of victories in all competitions, they have some sort of form to hang onto.
Stay tuned for team news within the next quarter of an hour ahead of our 5.30pm kick off, which you can watch live on Sky Sports.
Chelsea boss Liam Rosenior on Levi Colwill's fitness:
"I spoke to him this morning. He's really good. What a professional. He's working so hard. It's been brilliant to see him back on the pitch running. He's itching to get back. But we need to make sure he feels 100% perfect when he's back."
Could he return this season from a long-term knee injury?
"Yes, but it's step by step. I don't want to make promises I can't keep."
Nuno Espirito Santo believes he can get the best out of Adama Traore, and that the “unique” winger can boost West Ham’s bid to beat the drop.
Hammers boss Nuno has been reunited with Traore, having managed him at Wolves, after rescuing the 30-year-old from a disappointing season at Fulham.
“I’ve worked with him for many years, and I know him well,” said Nuno. “He’s unique – there aren’t many players with his ability one-on-one, or with his pace.
“I think he’s going to give us many things that we need. He possesses great threat, and he has great energy, not only on the pitch, but in the dressing room and at the training ground too. He’s a special person to have around.
“It’s not up to me to judge what’s happened to him before. I’m just happy to have him here.”
The Hammers briefly closed the gap to 17th-placed Nottingham Forest to two points last weekend after beating Sunderland, but Forest responded a day later by winning at Brentford to leave Nuno’s side five adrift of safety going into Saturday’s trip to Chelsea.
“We just have to focus on ourselves, and ignore what our opponents are doing,” added the Portuguese coach.
“We have to try to compete well, play well, achieve results and keep going. We can’t focus on what the other teams are doing, because we can’t control that.”
