Diego Costa signed for Wolves a month ago and made his debut for them last Saturday at West Ham. He did not score but casting minds back, Blues fans will recall many of the 20 goals he netted in the Premier League on the way to our 2014/15 title win, and then the same number again in the competition two seasons later when we also lifted the trophy.

Now, on the eve of the striker’s visit to his old stomping ground, Graham Potter who is planning how to prevent Diego Costa finding the net this time has given his opinion on the player.

‘I have a lot of respect for him, for his career, for what he's achieved,’ said the Blues head coach, speaking at his Friday press conference.

‘He's a Wolves player and he's going to come here and be ready to play. Everybody at this club knows how good he's been and I followed his career from afar and I have a huge respect for him and what he's achieved as a player.

‘He's one of lots of talented players at Wolves, especially in the forward line. There is a lot of attacking players there that can that can hurt you so we have to be ready.’

Potter been asked whether he thinks the 34-year-old [it is Diego Costa’s birthday today] will receive a good reception from the Chelsea fans.

‘I'm not sure, I would hope so,’ he responded. ‘Always when players have achieved something in a club you hope that, but that's not for me to decide. I'm focusing on our team and I thought the support the other night was fantastic so we are hopefully building on that.’

Helping to boost the Stamford Bridge atmosphere on Wednesday night was a goal from Pierre-Emerick Aubameyang which put us 2-0 up in the eventual 3-0 win against AC Milan. It was the summer signing’s second goal in two games and he is set to play as the Chelsea counterpart to Wolves’ Diego Costa tomorrow. Potter says his training pitch work has not specifically been about getting Aubameyang scoring goals.

‘It's more that we've been working with the whole group, laying the foundations in terms of how we want to be. The better the team functions, the more whoever is in the forward line has a chance of playing well and doing what he's there to do, which is to score of course but it's not the only thing he has to do.

‘A lot of that goes unnoticed but he does a lot of work for the team. We're happy for him that he's scoring and long may that continue.’
