Harlequins director of rugby Conor O'Shea has backed England prop Paul Doran-Jones to get even better at the Stoop.
The former London Welsh 27-year-old has agreed a two-year deal to switch from Northampton Saints in the summer as a replacement for departing James Johnston.
Enfield-born Doran-Jones started his career in the Leinster academy before moves to Old Deer Park and Gloucester ahead of his arrival at Franklin's Gardens.
He played for England U18s and made his full international debut against Argentina in 2009 - while at Kingsholm - and has since made three further appearances, touring South Africa with head coach Stuart Lancaster's squad last summer.
And O'Shea expects more plaudits to come his way a Quins.
"While we were disappointed to lose James Johnston we recognise the need to have an experienced player to come in to supplement the existing tight head talent we have at the club in Will Collier and Kyle Sinckler," he said.
"With that in mind we are very fortunate to be able to bring in a player of Paul's ability.
“Not only is Paul talented, at his age he will only get better. He comes from a fabulous club and has been coached by one of the best forwards coaches in the country so I have no doubt he will add greatly to what we have at Harlequins.”
Doran-Jones added: “I’m delighted to have the opportunity to play at the best club in the Premiership.
"The team play with smiles on their faces, a sure sign that they enjoy their style of rugby.
"I’m looking forward to being part of that, to improving my game and to working with the coaches and players to contribute to further success for Harlequins.”
