Schalke are closing in on the signing of Hungary international Adam Szalai after agreeing a fee with his current club Mainz.
The Royal Blues have been on the lookout for a striker to play alongside star man Klaas-Jan Huntelaar and general manager Horst Heldt announced on Thursday morning they have made progress in their pursuit of Szalai.
Heldt told Sport Bild: "Adam is with us for a medical after we reached an agreement with Mainz. It is just missing the contracts."
Szalai has reportedly negotiated a four-year deal with the Gelsenkirchen club and Heldt is excited at the potential of the 25-year-old.
"Adam has an incredibly good mentality and a good strike rate," Heldt said of a player who has netted 21 goals in 79 Bundesliga appearances for Mainz.
"We found last season we could not adequately replace Klaas-Jan Huntelaar when he was injured.
"With Szalai we are taking the next step. Competition is very important."
Schalke finished fourth in the Bundesliga last season and will play in the qualifying rounds of the Champions League.
Centre-back Robertson has arrived from Preston on a two-year deal while out-of-contract striker Tomlin will join up with his new team-mates on July 1 having finished as top scorer at Southend last season with 16 goals.
"We've been after a new centre half and Chris fits the bill," Adams told the club's official website.
"He's 6ft 3in, has got good experience in League One at Preston and is going to be a decent addition to the squad."
Following completion of the deal, Robertson was equally happy to have signed and was in confident mood about Vale's chances for the coming season.
"The club is on the up and there is a good atmosphere around the place at the moment with regards to the promotion last year, I am ready to get stuck in," the 26-year-old added.
Joining Robertson at Vale Park is 30-year-old Tomlin.
"The manager showed a massive interest in me," the London-born striker said.
"I was always told by friends and fellow experienced professionals that you have to go where you are wanted.
"Getting promoted, you've done really well last season, it's a good team and you've got some really exciting players so it's a pleasure to be here."
