Dan Walker is joined by Jermaine Jenas for this week's Focus Forum as they look forward to Tuesday's Champions League fixtures, with Arsenal and Chelsea in action.
Arsenal, who are bottom of Group F after losing their opening two fixtures, are at home to Bayern Munich and Jenas expects a tough night for Arsene Wenger's team.
He said: "I'm really worried about Arsenal. It's a must-win game."
Chelsea, who are third in their group, travel to Dynamo Kiev with Jose Mourinho's men looking to bounce back after losing to Porto in their previous Champions League match.
