Motherwell have completed the signing of striker Curtis Main from Portsmouth, but manager Stephen Robinson says he is still looking to bolster his attacking options following the departure of Louis Moult.

The 25-year-old Englishman arrives on an initial 18-month deal, after securing his exit from Pompey on Wednesday.

With the forward coming in as the Fir Park club’s first signing since losing their top scorer to Preston North End, Robinson is keen to stress that he hasn’t been signed as a direct replacement for Moult.

Instead, he will look to increase competition in the Motherwell attack further throughout the January transfer window.

“I’ve tried to sign him a number of times before and I am excited to finally be working with him,” Robinson said.

“I’ve brought him here to bolster our attacking options and get amongst the goals. He’s a strong, sharp, tenacious player with an eye for goal. If you look back on his career, he’s scored all different types.

“I am still looking to add more forward players to create real competition in that area of the field.”

Main came through the youth ranks at Sunderland, and has played for Darlington, Middlesbrough, Doncaster Rovers and Oldham as well as his most recent spell at Fratton Park.

But with Main finding first-team opportunities under Kenny Jackett increasingly hard to come by, he has decided to try his hand in Scottish football, and he is desperate to make an impression.

“I’m pleased to be here and I’m looking forward to this new challenge,” Main said.

“A few weeks ago, I heard about the interest, and it’s been back and forth with the club and myself but finally we’re here and I can’t wait to get started.

“There were a few options, but I felt this challenge, coming up here and testing myself in a new environment is something that really appealed to me.”
