The Blues welcome our London rivals to Stamford Bridge in the Premier League this weekend, hot on the heels of last night’s Carabao Cup clash with Arsenal in SW6.

The four players mentioned all missed that League Cup semi-final first leg, Palmer and James more through precaution, while Delap and Gittens were both unwell.

Rosenior was in the hotseat at Cobham on Thursday afternoon to preview Saturday’s visit of Keith Andrews' Bees, and our head coach provided an update on the quartet mentioned above.

‘With Reece and Cole, both of them are training today so we just need to assess them after training and make sure they come through all of the protocols they need to come through,' Rosenior told the gathered media.

‘But it will be great to have them back in the squad and at the moment, it looks like they could be.'

He added: ‘Liam is still at home recovering at the moment, as is Jamie Gittens. Our club doctors are doing everything they can to contain what looks to be a virus, because some members of our staff have gone down with it as well.

'We had a meeting today with the players about the basics such as washing their hands because it is really important and hopefully we can contain it. We have a busy period, so we need everyone ready to go, fit and healthy.'

Meanwhile, Rosenior also updated on the progress of Romeo Lavia, who is working his way back up to fitness having been sidelined since early November.

While the midfielder isn’t close to a return to action just yet, our head coach confirmed that he is doing his rehab on the grass and stated he’s excited to work with Lavia when he is back with the group fully.

‘Romeo is on the pitch, he’s not with the group yet but we can see him out on the grass doing his rehab,’ Rosenior added. ‘He is looking really, really good.

'I love him, firstly as a lad but also as a player. He's someone I would love to work with in the long term because he's just an outstanding footballer.

'The most important thing for him now is to make sure we don't push him too hard, so that when he does come back, he's back for good and I can get some real work into him tactically.

'For me, he's a player I can't wait to have back in the group, and I'm really, really looking forward to having him back with us.'
