Both Pulisic and Ziyech were handed rare starts on Saturday for Chelsea’s trip to Elland Road to face Leeds United, but Carney and Townsend were underwhelmed by their performances.
Tuchel subbed off Pulisic and Ziyech in the second-half of the goalless draw, with Reece James replacing Pulisic and Timo Werner coming on for Ziyech.
Carney and Townsend both believe the match was further evidence that Pulisic and Ziyech will ‘struggle’ under Tuchel and may even be inclined to move on at the end of the season.
Chelsea signed USA international Pulisic from Borussia Dortmund in 2019, while Ziyech arrived at Stamford Bridge last summer from Ajax.
Former England star Carney told Premier League predictions: ‘It’s going to be difficult. Ziyech is at his best when he’s on the right-hand side and cutting in to his left foot.
‘They are two players who haven’t featured that much, the manager has gone “right, you’re starting, here’s your opportunity”. For me, they didn’t take it.
‘I thought Pulisic was the better out of the two but they’re both lacking confidence. Pulisic has been linked [with a transfer] this week which doesn’t help at times.
‘They didn’t take their chance. I know it’s against a very difficult Leeds side but they didn’t do enough and I do think they will struggle, I really do.
‘I don’t think Ziyech has felt settled, he’s had injuries as well. He looked hesitant, he didn’t look himself, he just doesn’t look right.
‘Does he know something else or has the manager told him he’s down the pecking order? I think one of them could go.’
Townsend, the former Republic of Ireland midfielder, added: ‘I’m not sure how easy this is going to be for them under Thomas Tuchel.
‘I think both of these guys, with the Tuchel set-up, have to get going pretty quickly, I really do. I’m not sure they’re going to do that.
‘I wouldn’t be surprised to see one of them leave this summer. I wouldn’t be surprised at all.
‘I don’t think Pulisic wants to sit on the bench and I think Ziyech will get bogged down a bit. His body language hasn’t been great.’
