Dutch midfielder Siem de Jong has said that Newcastle can’t sell their best players this summer if they want to make progress.

Speaking about what has happened at both Newcastle and his previous club Ajax in recent seasons, de Jong points to the benefits of keeping your best group of players together which gives them a chance to improve as a team.

Siem de Jong speaking to the Chronicle:

“It is about players leaving and getting injured.

“I had it at my old club (Ajax) as well, we were champions four years in a row, lost the three best players every year, so we needed to build and start again.

Keeping the group together:

“It happened here as well, you lose a couple of players to bigger clubs and it’s difficult.

“Hopefully we can get a group together here that stays together for a couple of years, gets used to each other and really improves.”

However, de Jong says there are positives with Newcastle still having pulling power:

“I think players will want to come to Newcastle, it is a big club and I think everybody in football knows that it is a big club.

“The last few years are a little bit up and down.”

The United midfielder says that if you are constantly selling your top stars, it then takes time for new players to blend in with their new teammates.

Newcastle found this to their cost this season, when after buying not one first team squad player over the course of the 2013/14 season, big changes of personnel last summer saw United have five new signings involved on the opening day of this season.

Daryl Janmaat, Jack Colback, Emmanuel Riviere and Remy Cabella all started the game against Manchester City, plus Ayoze Perez came off the bench.

It would very likely have been half a dozen if Siem de Jong had been fit enough to be involved.

Keeping your best players and replacing the weaker ones with better, is the only way to go.
