CHELSEA must ditch their international break blues if they are to get one over on old boss Andre Villas-Boas, according to Branislav Ivanovic.
The Premier League has this weekend off while its top stars train with their home nations for a round of World Cup qualifiers.
Chelsea have dropped points in four of their past seven matches that followed an international break and their only blip this season was the goalless draw with QPR.
That stalemate came after September’s international hiatus and Blues defender Ivanovic is aware of the problem ahead of next weekend’s clash with Tottenham.
“The international break is a good time to enjoy our position but there is a very important period coming up for us after the break,” said Ivanovic.
“We have some very tough games and they will be a great challenge for us. At the moment it’s OK but the next two games will be very, very tough.
“It’s always very difficult to play the game after the international break, but especially when it’s big opponents like Tottenham away.
“Our games against Tottenham were very interesting and tough for both sides even before Andre [Villas-Boas] went there. Now it is especially so for both sides with our ex-manager.
“It will be difficult in one way and in the other way we know what is the idea and what we can expect of them.
“This game will be decided by things like when you are back from your international duty and how tired you are – the small details. So it’s going to be tough for us.”
After Tottenham, Chelsea travel to the Ukraine to play Shakhtar Donetsk, followed by back to back visits from Manchester United in the league and Capital One Cup.
