Chelsea boss Jose Mourinho admits his change in formation for this season could mean even less first team chances for Andriy Shevchenko.
Mourinho said: "If we play 4-3-3, it leaves Sheva in a fight with Drogba and Claudio Pizarro, that's obvious. If we play 4-4-2, then Sheva, Pizarro and Drogba will fight for two positions.
"But I don't want to speak about individuals at this moment. Some players get their form after two days, others take longer."
