Antonio Rudiger has indicated he is ready to fight for his place in the Chelsea backline, having fully recovered from a groin injury he has been carrying for weeks now.
The German international was back in training this week and is in contention to feature when Chelsea play Watford on Saturday.
He will, however, have to battle to have his starting role back, following Kurt Zouma and Fikayo Tomori's excellent partnership in his absence.
The two started on a shaky note, but have grown in recent weeks as the Blues went for a seven-match winning streak which was only soiled by Manchester United in midweek.
"It has been very long now [the absence]. Even with my cruciate ligament rupture, I was not out for so long. I'm itching [to play] but very patient."
The Blues have also been boosted by the return of french midfielder N'Golo Kante, who has also been missing since the 4-1 win away to Southampton.
Chelsea will on Saturday travel to Vicarage Road for another English Premier League showdown, hoping to bounce back from the 2-1 defeat in the Carabao Cup.
They are currently fourth on the standings on 20 points, eight adrift of League leaders Liverpool.
