RB Leipzig took a brutal dig at former player Timo Werner and his new club Chelsea, after they were beaten 2-1 by Arsenal in the FA Cup final.

Werner was at Wembley for the final and watched on as a magnificent brace from Arsenal captain Pierre-Emerick Aubameyang sank Chelsea's hopes of lifting the trophy.

The German was spotted on his phone towards the end of the game and Leipzig suggested Werner was having second thoughts about his move to Stamford Bridge, tweeting a picture suggesting he was messaging them.

Timo Werner was spotted on his phone during the game

"With Ziyech and Werner, Chelsea will try to be more competitive. If you had told me that it was a player of my profile who was coming, I would have been worried. It is not.

"As other teams play in a compact way against us, it’s not bad to have a big, a fulcrum that can make the link. But I’m not naive: Werner didn’t arrive to sit on the bench.

"I’ll do everything so that Lampard finds himself in a complex situation when it comes to making his selection."

In his first interview at Stamford Bridge, Werner said: "The style of the Premier League is very fast and my speciality is that I am really fast so I think it is perfect for me to play here.

"It is another league in another country so I can improve myself to bring it to another level, so those are the reasons I come to the Premier League and to Chelsea.

"I’m very happy to be here and I’ll try to score as many goals as I can for Chelsea, that is the big reason why they bought me, to bring the goals I scored in Leipzig here, and maybe score more goals than there."
