January signing Mudryk seemed to like an Instagram post criticizing Cucurella after expressing his frustration with his teammate during Saturday’s disappointing 1-1 Premier League draw at West Ham.

Both players have traveled to Germany for the Blues’ Champions League round of 16 first leg against Borussia Dortmund.

Speaking on the eve of the game at Signal Iduna Park, head coach Potter stressed that the pair need time to get acquainted with each other’s games and dismissed suggestions of a split at camp.

“There is no problem in terms of anything sinister,” he told a news conference.

“If anything, it’s just that teammates understand each other, it’s a pretty common problem, I would say: when to pass, at what point, at what time.

“Playing against a back five, West Ham makes it difficult for you to access perhaps the wideman’s feet and it’s just an understanding of when to play space or how to make runs.

“Mykhailo, that’s just his third game with us, so no problem. It’s more of a comprehension challenge, which is quite easy to understand when you recognize the context we’re in.”

Left-back Cucurella has struggled to regain his form at Stamford Bridge since a reported £60m summer move from Potter’s former club Brighton.

Meanwhile, Ukrainian winger Mudryk is in line for his first European action for the big-spending Blues following his recent arrival from Shakhtar Donetsk for an initial £62m.

Chelsea, who have recruited a host of new players under the ownership of Todd Boehly, sit 10th in the top flight with just two wins from their last 13 league outings.

Potter is hopeful the two-time Champions League winners can put aside their poor domestic form in Dortmund.

“It’s the knockout stage of the Champions League, the absolute pinnacle in terms of gameplay,” he said.

“A great test, playing a fantastic club and team in front of about 80,000 here, so a wonderful occasion.

“We are all looking forward to the game, we all understand the challenge ahead, but we are very excited about it.”

Raheem Sterling has stayed in London due to injury but defender Wesley Fofana, who hasn’t played since October, is among the travelers, while midfielder Denis Zakaria could turn up after a three-game absence.
