Antonio Conte expects Antoine Griezmann to provide Chelsea a stern test when they face Atletico Madrid at Stamford Bridge on Tuesday.

The France star has three goals and an assist in his last two LaLiga matches and scored in the crucial 2-0 win over Roma on matchday five of the Champions League group stage.

Griezmann's return to form has come at an important time for Diego Simeone's side, who must win in London this week to have any chance of progressing to the last 16.

Conte is eager not to put too much focus on stopping the former Real Sociedad star but admits he is "a fantastic player".

"The situation has changed," Conte told a news conference. "Three games ago, there was a Griezmann problem because he didn't score. Now he's scoring.

"Griezmann is a top player, a fantastic player, playing in a great team and showing he is a top player. We must pay great attention not only to him but to all the players."
