Chelsea midfielder Frank Lampard was thrilled to help his side get back to winning ways after the international break.
The veteran was involved in England's triumphant World Cup qualifying matches, starting in the convincing victory against Montenegro before coming off the bench to help secure a crucial victory against Poland.
Lampard admits it can be difficult switching focus from one competition to another, and believed that Cardiff City took advantage in the early stages at Stamford Bridge.
However, Jose Mourinho's side came good to secure a 4-1 victory against the Bluebirds, and the former West Ham starlet believes it could prove to be an important victory.
"It was a very tough game for us. Sometimes after internationals you can be a bit slow to start, but I thought Cardiff were very well organised. Having gone 1-0 down, it's a very good result for us," Lampard told Sky Sports post-match.
"It is difficult, but we've got a big squad here. It's important that we try and stay fresh, the manager changes it sometimes. If you get a positive result internationally, which a lot of us did, you can bring that back with you.
"I think the main thing is focus and concentration. We want to stay at the top of the league, we don't want to lose ground."
It was Lampard's midfield colleagues who got the important goals for the Blues, with Eden Hazard (2) and Oscar getting on the scoresheet. Samuel Eto'o also notched a controversial equaliser.
The victory also moved Chelsea up to second in the Premier League table, with 'the special one's' side just two points behind Arsenal at the top of the league. They are ahead of Liverpool on goal difference.
