Graeme Souness has warned Manchester City that Chelsea could be their biggest title rivals next season and he believes they are only getting stronger.
Chelsea have only lost once since Thomas Tuchel replaced Frank Lampard at the end of January and look set finish in the Champions League places despite a poor start to the campaign.
Tuchel's tactical innovations have caught the eye in the Premier League, whilst the German coach is searching for a way to get the best from big-money additions Kai Havertz and Timo Werner.
The former was on target in an impressive 4-1 win over Crystal Palace on Saturday night, prompting Souness to suggest Chelsea could be City's biggest threat next term.
"When you look at the team that started for Chelsea and their subs, I would put them as having the second-best squad in the Premier League behind Manchester City," Souness said.
"I think City have an incredible squad, and I'd go so far as to say the best I've ever seen in English football. But I think Chelsea have the second-best group.
"Other than having a 25 goals a season man, I think they're pretty near. If they get [a new goalscorer] they'll be very dangerous from now on.
"I think they're in a great place, they'll do the business on Porto and get through to the semi-finals for the first time in a long time."
"I think they create so many chances, you look at the chances they created today and the ball retention, they need someone. They're not always going to have those chances," Souness added.
"They need someone who can put the ball in the net better than what they've got right now, that's the only thing missing from that group of players.
"Then you factor in Mason Mount, 21, (Callum) Hudson-Odoi, what's he, 20, 21? (Christian) Pulisic, (Hakim) Ziyech, they've got a lot of young players who should theoretically only get better next year."
