Chris Smalling feels England have the potential to improve on their performance against Germany.
Per Mertesacker's first-half header ensured England ended 2013 on a low as the Germans ran out 1-0 winners at Wembley.
– England defender Chris Smalling
I think Germany are one of the favourites for the World Cup.
They are a big nation. I don't know (how far we are behind them).
They didn't have all their players available and we didn't have all of ours so there is a lot more that both sides can give.
