Tuchel added: "He misses way too many camps with injuries, and I only want to rely on what I witness and see within in my team, and for that you have to be in camp. And if you're not in camp, there is a next level to impress that you cannot achieve because you can only do it when you are actually on the pitch with me. So yes, it is a missed opportunity."
Back in London, Chelsea have several other key players unavailable. Alonso is currently without Joao Pedro, Reece James, Moises Caicedo, Marco Palestra and Emmanuel Emegha. Injuries have severely disrupted Gittens following a £51.5 million transfer from Borussia Dortmund.
