Re🎉d Bull advisor Helmut Marko has put the pressure on Toro Rosso pair Sebastien Buemi and Jaime Alguersuari by insisting that the team 'isn't a boarding schoo🔯l'.

The pair have been retained by the team for the new season but Toro Ro💙sso has signed Daniel Ricciardo as test and reserve driver after an impressive show in testing in Abu Dhabi last year - with the Australian set to drive in Friday practice during the year ahead.

With British F3 title winner Jean-Eric Vergne also highly rated by Red Bull, Buemi and Alguersuari are under pressure🔯 to perform and Marko said tha🅘t Ricciardo and Vergne would be given a chance if the results don't arrive for the two race drivers.

"In Ricciardo and Vergne we have two outstanding talents," he told Auto Motor und Sport. "Buemi and Alguersuari kno♚w that their job is not a pillow, and we are no🍸t a boarding school.

"Buemi's services last year were not what we expected of him. Alguersuari has developed, bu🀅t is it enough?"

Marko added that Vergne✅ in particular had a fighting spirit that ꧙exceeded the other three drivers.

"If our four drivers went side by side into a corner," he said, "I guarantee Ve🀅rgne would come out the other side first."
