The Italian took charge of Aston Villa last month.
The Italian was confirmed as the club’s new manager last month following Tony Xia’s takeover at Villa Park.
There is a sense of quiet optimism about his appointment, with fans hoping his experience of success in the Championship with West Bromwich Albion will stand them in good stead for the challenges ahead.
With pre-season now underway, the Villa manager is working hard to get his side prepared for life in the Championship next season.
And Clark says so far the impression he has made on the squad has been a positive one.
“Roberto has made a very good impression with the lads. He’s a good man and good manager,” he told avfc.co.uk.
“He’s won the European Cup with Chelsea but probably more relevant for us is the fact he got West Brom promoted to the Premier League. Here’s to another promotion on his CV by the end of this season.”
It will be interesting to see if Di Matteo can add another promotion to his CV next season, with the Championship title eyed by several clubs.
Villa will be among the favourites, as are Newcastle United, while the likes of Derby County, Sheffield Wednesday, Norwich City and several others will be keen to fight all the way.
Indeed, Villa be a big scalp many clubs will want to take, and it is likely to be a tough season ahead for them.
