Chelsea boss Xabi Alonso has been speaking to the media before Saturday's Premier League game against Tottenham at Stamford Bridge (17:30 BST).

Here are the key lines from his news conference:

• Alonso began by providing an update on the fitness of goalkeeper Emiliano Martinez, who suffered a broken jaw in the win over Everton last weekend: "He's doing better. He had the surgery. Day by day he's feeling better, but we have to wait. A few weeks, hopefully less than more, but we need to wait. The good thing is he is feeling better. We need to listen to the specialists. Considering it was a bad one he is doing good."

• The Blues boss added Malo Gusto is "fine" and available, while fellow full-back Pep Chavarria is "still training a little bit more but he is not going to make it".

• On Emmanuel Emegha, who is yet to make his debut after arriving from Strasbourg in the summer: "He's feeling better but we need to wait."

• On 21-year-old goalkeeper Mike Penders, who will start in place of Martinez on Saturday: "He is ready. He has been training well, played a couple of cup games where he has showed he has a good level. In a few minutes against Everton he showed his personality and qualities. That's why we have a squad for these situations, and we are fully convinced Mike can play very well."

• Asked about Penders not being considered ready to be first choice in the summer, Alonso responded: "We wanted to have the best possible options so we moved for Emi. Mike is a keeper for now and for the future, learning with an experienced keeper like Emi. We are happy with Mike, he is prepared."

• On comparisons being made between Penders and international team-mate and former Chelsea goalkeeper Thibaut Courtois: "A lot. Not just for the nationality - for the stature, both left-footed, both dominant in the air. I spoke with Thibaut at the World Cup and even he said he can see similarities with Mike."

• On his first taste of the rivalry with Spurs: "Every derby is special, you feel the energy and excitement from the stands. We need to use that energy on the pitch because we need to connect well. We need to have good emotional control as well because there is a lot of passion and commitment from both sides. Playing football with heart is what we want."

• On opposition coach Roberto de Zerbi, he added: "He has very clear ideas. It is still early days with many things to play in the season. We will see tomorrow."

• Asked if he is aware of Chelsea's strong Premier League record against Tottenham: "I knew about it, but tomorrow is another game. We need to prove again that we can continue that run and knowing it is a special game so we need to play with heart, head and intelligence."
