Chelsea lost five of their last six games in all tournaments and have drawn a blank in front of goal in all five of those defeats as pressure grows on Rosenior to turn the side around. The Blues shipped three goals away at Everton in their last Premier League road trip and as their Champions League dreams slip away, Rosenior has not given confidence to fans as he reveals that striker Joao Pedro could miss the clash. "Joao will be a late call. "He was on the pitch today, we will make a decision tomorrow morning. "Este (Estevao) is definitely out for tomorrow. We are doing further tests. Enzo (Fernandez) is absolutely fine." The Chelsea boss also spoke on Levi Colwill, who is closing in on a return to action having suffered a knee injury in August. "Very hopefully, yes, we can see him before the end of the season. "He played 60 minutes (in recent behind-closed-doors Under-21s match) which is a very good start for him. "We want him to be involved for the U21s on Saturday too." The main concern for the club is Pedro, who was not part of the squad for Saturday’s 1-0 home defeat to Manchester United due to a thigh injury. Without him, the Chelsea side look toothless in attack with the likes of Cole Palmer and Alejandro Garnacho looking clueless going forward for Rosenior who cannot get a grip on his failing side.
