Sky Sports expert European predictions: How will Arsenal and Chelsea finish?

Charlie Nicholas previews Chelsea and Arsenal's Europa League matches. Here's how the former Arsenal and Scotland star sees the big games going.

Arsenal vs Napoli

Our home form is excellent, so I am pretty confident when we play at home. I have not been confident and never will be with this team defensively. They do not know how to defend.

Napoli are not brilliant. They had a draw at home at the weekend and are second in Serie A, but are not as strong as they used to be.

Unai Emery - please just play Pierre-Emerick Aubameyang and Alexandre Lacazette. He said how they are a strong combination but he is not playing them together. I don't get the decision to play Mohamed Elneny and Henrikh Mkhitaryan.

Aubameyang, Lacazette, Aaron Ramsey and Mesut Ozil must start together on Thursday, and if they do, Arsenal will win.

Charlie predicts: 3-1

Slavia Prague vs Chelsea

I think the manager is going after this and Maurizio Sarri may want to win something, especially if he goes at the end of the season.

I would play Eden Hazard and Olivier Giroud. I would also play Callum Hudson-Odoi and those would be the three up front and I would tell them to go after it - I expect that to happen.

They are still not the best at the back but I expect them to win comfortably.

Charlie predicts: 1-3
