Nigerian-born Chelsea striker, Tammy Abraham, says new recruits, particularly midfielder Kai Havertz and forward Timo Werner need time to develop an understanding with the rest of their teammates.

A congested fixture list amid the COVID-19 pandemic has not helped the process, Tammy further said.

The pair have had an underwhelming run of play recently, eliciting raised eyebrows about their hefty transfer fee.

Chelsea spent heavily in the close season to bring in the likes of Havertz, Werner, defender Ben Chilwell and winger Hakim Ziyech, but the London club sit ninth in the Premier League with 26 points from 17 games.

Germany international Werner has come in for sharp criticism due to a dip in form after failing to score in his last 12 games in all competitions, but Abraham said all of Chelsea’s new signings need time to settle.

“We have hardly had any time to train together and to work out how each other play so we’re just taking every day as it comes at the moment,” Abraham told Chelsea’s website.

“Every game we play; we’re learning new things about each other. I’m starting to understand them more and they’re starting to understand me more so hopefully we drive each other and be the best we can be.”

Chelsea, who have lost four of their last six league games, take on Morecambe in the FA Cup third round on Sunday before a league trip to Fulham on January 15.
