Chelsea boss Jose Mourinho has no injury concerns ahead of his side's Premier League clash against Southampton on Sunday.

The Blues have been very lucky to have minimal number of injuries this season even though Mourinho has been playing almost the same team in most of the matches.

In September/October, the Blues did face a striker injury crisis, with Diego Costa and Loic Remy both being sidelined at the same time, but club legend Didier Drogba shouldered the goalscoring load till the two forwards returned.

Apart from that, the Blues have had no major injury problems this season despite them being involved in a lot of competitions.

Although currently there are no players on the sidelines for Chelsea ahead of their Premier League trip at the Saint Mary's on Sunday, Mourinho is likely to make some changes for this game as this is the Blues second game in a couple of days.

Andre Schurrle, John Obi Mikel, Filipe Luis and Didier Drogba are some of the players who could be given a nod for the match against Southampton.

Meanwhile, Mourinho says that he is extremely pleased with Eden Hazard's progression this season, insisting that the Belgian playmaker's success is due to him enjoying the game rather than thinking about pressure or responsibility.

"He's a happy guy on the pitch, he doesn't feel the pressure, he doesn't feel responsibility, he just wants to enjoy it," the Portuguese told the Blues' official website.

The former Real Madrid boss feels that the 23-year-old energy levels and commitment are same in the first as well as the last minute of the game.

"He plays in the first minute like he plays in minute 90, it doesn't matter the result, fantastic, no pressure, and that's a good feeling for me," he said.

Mourinho also feels that Hazard has gained more qualities than he has lost since coming to Stamford Bridge in the summer of 2012.

"Credit to him," added Mourinho. He didn't lose his spontaneity, he didn't lose his happiness, he didn't lose his creativity, none of his good qualities, but he won some other qualities.

"Even physically look at him, he's a small guy but he's very strong. He scores with his head, jumps well, he's strong to hold off contact from opponents."
