Roberto Di Matteo and Oscar Garcia are the latest names to be linked with the Aston Villa managerial vacancy.
Villa are still on the lookout for a permanent successor to Remi Garde as they prepare for life in the Championship next season following their relegation from the Premier League.
Former Leicester chief Nigel Pearson had been the frontrunner for the job, but there has been no movement on that front as speculation claims he is waiting to see if Aitor Karanka remains in charge of Premier League new boys Middlesbrough this summer.
As a result more names are being linked with 45-year-old Di Matteo, who guided rivals West Brom to promotion from the Championship during his two-year spell between 2009-11 and led Chelsea to Champions League glory in 2012, seeing his odds tumble.
The Italian has not worked since leaving German outfit Schalke last year and would be able to step straight into the void immediately.
Meanwhile Spanish tactician, Garcia, has also been mentioned after he recently guided Red Bull Salzburg to the Austrian title.
The 43-year-old, who has experience of managing in the Championship after taking Brighton to the play-offs in 2014, is believed to be unhappy at losing his key players to fellow Red Bull-owned outfit RB Leipzig in Germany.
And a new challenge at Villa could appeal to Garcia, who is also said to be wanted by other clubs in the Championship and from Turkey and Greece.
