France international Digne arrived at Everton from Barcelona this summer with significant pedigree.
As well as spending two seasons with the Catalan giants, he had previous spells at Serie A team Roma, and with Paris St Germain and Lille in his homeland.
The 25-year-old has swiftly adapted to life in the Premier League, with his eye-catching Toffees form suitably impressing France boss Didier Deschamps, who has named Digne in his past two Les Bleus squads.
Pienaar is convinced scrapping for a spot in the Everton starting XI with a player of Baines’ calibre has served to elevate Digne’s performances.
“Lucas’s mission now is to keeping playing at the top of his game,” said Pienaar, who scored 24 goals in 229 games for the Blues.
“He knows Baines is ready to step in again. It’s good to have competition, and for the team in general to keep the players sharp, so they can perform every week.
“Lucas has played for very, very big clubs like Barcelona, he knows how to deal with the pressure. They are similar types of player – both strong in defence and going forward - and also with set pieces and scoring goals.
“It’s just a plus for the Club to have two players of that quality fighting for one position.”
Baines is in the midst of his 12th season as an Everton player, having signed from Wigan Athletic in 2006. His appearance in the Cup victory over Lincoln was his 409th for the Club – only 15 players in Everton’s history have turned out more times for the Toffees.
Pienaar believes this experience is invaluable for the Blues, highlighting Baines’ status as a role model off the pitch, as well as his quality on the field of play.
“Knowing Leighton, he’s always helping the younger players and I’m sure he’s helping Lucas as well as English football is a bit different compared to the Spanish league,” he said.
“He has got a big voice in the dressing room.
“It’s good to have senior players in the team and having a player like Leighton is good for all the young players coming through.”
