Newcastle United sign Switzerland international Fabian Schar - Rafa Benitez also closing in on striker

As reported by Sky Sports, Japan international Muto is on a flight to Newcastle from Tokyo after United agreed a deal with German outfit Mainz for the striker who netted eight goals in the Bundesliga last season.

The move, expected to go through by the end of the week, is subject to the player passing a medical and being granted a work permit, although that is not thought to be a problem.

Speaking to the Japanese press before his departure, Muto said of the move: "I can't say yet, but I should be able to deliver good news soon.

"I believe I'll grow as a player if I put myself in a competitive environment.

"My goal is to net 10 goals, a number I haven't reached during a season (overseas)."

Meanwhile, United have confirmed the signing of Schar for a reported fee of £3.5 from Deportivo La Coruna.

The 26-year-old said: "I’m really happy to be here. The club is a really big club for me. It has a big name, and it is a brilliant chance for me.

"I’m not like a typical defender. I, of course, defend, but I’m quite good with the ball – I like to play, I want to build up the game from behind, and I think that is a strength of mine. I have also scored some headers – that could also be a strength and hopefully I can use it here."

"I hope to start training with the team soon, and I’m looking forward to everything that’s coming. At the moment, I just want to get started."

Schar becomes Rafa Benitez's fourth signing of the summer.

Martin Dubravka's deal from Sparta Prague was made permanent in May for a fee of around £4million then Ki Sung-yueng came in from Swansea City followed by a loan deal for Chelsea's Kenedy.
