Jamie Carragher believes Jose Mourinho will continue his remarkable 'second season syndrome' by guiding Chelsea to Premier League glory this season.
Mourinho won both his Champions League winners medals in his second season with Porto and Inter Milan while he toppled Pep Guardiola's Barcelona in La Liga at the second time of asking.
Liverpool legend Carragher believes Chelsea's summer signings means they are the favourites to reclaim their first league title since 2010, when Mourinho's successor at Madrid, Carlo Ancelotti, lifted the trophy with the Blues.
"They won nothing last season but to go that close in the Champions League and the league without a recognised striker scoring regularly was remarkable," Carragher told the Daily Mail.
He added Mourinho's decisiveness in the transfer market signing Diego Costa, Cesc Fabregas and Filipe Luis were the hallmarks of a champion.
Arsenal, however, still have work to do before they can seriously be touted as title contenders. Carragher questioned goalkeeper Wojciech Szczesny as well as Arsenal's key players, including Mikel Arteta and striker Olivier Giroud.
"The spine comes up short. They spent more time at the top than any other team last season but still came up short," he added.
Of his beloved Liverpool, for whom Carragher made 700 appearances and won 11 trophies, including the 2005 Champions League, the former England defender said the Reds will miss Luis Suarez and need to add more firepower.
"They are a lesser team without him [Suarez], but looking at the signings Brendan has made they are probably now a better squad... But I worry if Sturridge gets injured. I think Brendan might need to address that," the 36-year-old said.
Manchester City, Carragher believes, are Chelsea's main rivals for the league crown providing Yaya Toure can continue his heroics for the Mancunians, while he expects their city rivals Manchester United to be a totally different proposition to last season with Louis van Gaal at the helm.
"I admired the way he worked with Holland... I see him doing the same at United. Getting Van Persie and Rooney on the pitch in a system that works for them by going to a back three," Carragher added.
