Arsenal winger Alex Oxlade-Chamberlain says they must be careful facing Southampton striker Ricki Lambert today.

Oxlade-Chamberlain has warned his team-mates of the goalscoring threat of old pal Lambert.

He said: "Rickie Lambert is a natural goalscorer. He has got the physique and is good in the air - a typical old school centre­-forward.

''Fonte is playing well and the manager is doing good things so I think they will stay up. I hope they do anyway."
